What is the difference between power specific UPS and power inverter

Generally speaking, UPS is also a kind of inverter, UPS is equipped with a battery, when the power supply is interrupted, the battery can continue to supply power for a certain time, so UPS is a small-capacity uninterruptible power supply.

A pure high-power power inverter converts direct current into alternating current, without a battery.

In the national standard DL T 1074-2007, DC and AC integrated uninterruptible power supply equipment for electric power, the concept of power UPS and power inverter is defined.

The chapter introduces the definition of electric UPS, that is, electric power ongoing, AC uninterruptible power supply, a power supply device composed of rectifiers and inverters, etc., which cooperates with the battery pack of DC power supply to provide uninterruptible AC power supply that meets the requirements. Due to the connection to the battery pack of the non-node system, the DC input part of the device is isolated from the AC part.

This chapter introduces the power inverter, or INV for short, which is an AC uninterruptible power supply for power without a rectifier.

The difference between power UPS and power inverter is that power UPS is a double-conversion working mode, zero switching, and mains mode output voltage stabilization function. The power inverter is a backup mode of operation, there is a switching time, and when the mains is present, it does not have a voltage regulation function.

In Appendix A, the differences between the application of electric UPS and electric inverters are described.

A1, accident lighting equipment should choose the inverter of backup operation, data processing equipment should choose double conversion power UPS, according to the importance of the equipment can choose different configuration methods.

Refers to uninterruptible power supply, which has three classifications:

1. Passive backup UPS power supply.

Refers to the parallel connection of the inverter between the mains and the load, and simply uses it as a backup power source. This kind of UPS power supply, when the mains is normal, the load is completely and directly mains power, the inverter does not do any power conversion, and the battery is powered by an independent charger; When the mains power is not normal, the load is completely powered by the inverter.

It means that the inverter is connected in parallel between the mains and the load, which plays the role of backup power supply, and the inverter acts as a charger to charge the battery. Through the reversible operation mode of the inverter, it interacts with the mains power, so it is called interactive.

3. Double conversion UPS power supply.

Refers to the inverter connected in series between the AC input and the load, and the power supply is continuously supplied to the load through the inverter. The power supply mode of this UPS power supply is as follows: when the mains power is normal, the mains power is supplied to the load through the rectifier and inverter; When the mains power is abnormal, the accumulator supplies power to the load through the inverter.

Power inverter principle:

The power inverter relies on the internal electronic circuits to automatically realize the battery protection function. When the power inverter is in use, if there is a shutdown and alarm phenomenon, the following items should be checked:

1. Whether the power of the electrical appliance driven exceeds the rated power value of the inverter.

2. Whether the power inverter is well connected with the battery and electrical appliances.

3. Stop the machine during use, whether it is a temperature alarm, and you can continue to use it after stopping for a period of time.

When using a power inverter, pay attention to the voltage value of the battery-powered system, and read the manual carefully before use.

An inverter is a current conversion device that converts direct current to alternating current or vice versa.

UPS is a kind of uninterruptible power supply device, its principle is battery + inverter, the mains is converted to direct current by the inverter, and the direct current is charged to the battery.

There is also a word "voltage regulator" to mention here The voltage regulator can keep the unstable mains power at a fixed voltage through the voltage stabilizing device, which is very beneficial to the normal use of electrical appliances.

In civil use, voltage regulators are widely used, such as refrigerators and air conditioners, and many users install high-power voltage regulators in the main incoming line, so that all Hanque electrical appliances are protected. We know that especially after the power is cut off and restored, there will be an overload peak in the voltage, and the voltage will be too high in an instant, which is the reason for the damage of most electrical appliances.

UPS power supply is suitable for electrical appliances such as computers that may cause data loss due to unexpected power failures, such electrical appliances generally start data loss caused by 1 second power failure, and UPS can be used to supply power supply into Changqixing protection, such as servers, signal towers of Mobile Unicom, etc.

Some equipment with low requirements will also use some backup power supply systems, such as emergency exits, which respond a little slower, some use backup engines for more than ten seconds to power supply, and some use batteries. For example, the power plant's own power system is equipped with backup diesel units worth millions of yuan, which are preheated all day long, and in the event of an unexpected power outage, the power supply is guaranteed to be restored in more than ten or dozens of seconds.

But the inverter is rarely used alone because it is only a current conversion device, a typical example is the on-board power supply, which is an inverter, which takes 12 volts of direct current from the cigarette lighter of the car and converts it to 220 AC power for AC appliances, such as laptops.

First, the composition is different.

1. Power inverter: composed of inverter device.

2. UPS power supply: main, bypass, battery and other power input circuits, rectifier (REC) for AC DC conversion, inverter (INV) for DC AC conversion, inverter and bypass output switching circuit and energy storage battery.

Second, the use is different.

1. Power inverter: The power inverter is not only suitable for the vehicle debate bulk load system, as long as there is DC12V power supply, the power inverter can be used to convert DC12V to AC220V alternating current, which brings convenience to your life.

Third, the working principle is different.

1. Power inverter: realize DC input, and then output AC, the working principle is the same as that of switching power supply, but the frequency is within a certain range, for example, if the frequency is 50Hz, the output is AC 50Hz. An inverter is a device that can change its frequency.

2. UPS power supply: the rectifier device adopts thyristor or high-frequency switching rectifier, which has the function of controlling the output amplitude according to the change of external power, so that when the external power is changed (the change should meet the system requirements), the output amplitude is basically unchanged rectifier voltage. The purification function is completed by the energy storage battery, and because the rectifier cannot eliminate the instantaneous pulse interference, there are still interference pulses in the rectified voltage.

1. Inverter introduction:

The inverter is a DC-to-AC transformer, which is actually a voltage inverter process with the converter.

The inverter converter converts the AC voltage of the grid into a stable 12V DC output, while the inverter converts the 12V DC voltage output by the adapter into high-frequency high-voltage AC; Both parts also use the more widely used Pulse Width Modulation (PWM) technique. The core part is a PWM integrated controller, the adapter uses UC3842, and the inverter uses TL5001 chip. The operating voltage range of TL5001 is equipped with an error amplifier, a regulator, an oscillator, a PWM generator with dead zone control, a low-voltage protection loop and a short-circuit protection loop.

Inverter function description:

When it comes to inverters, everyone is no stranger, inverters are the earliest power conversion tools, which can output the inverter of direct current from the battery to the load equipment;

The inverter cannot charge the battery, and the charger must be configured separately;

The inverter is generally used for small electrical equipment, and the stability is not very good, and it is generally used for electrical equipment with low requirements;

2. UPS power supply introduction:

UPS (Uninterruptible Power System Uninterruptible Power Supply), that is, uninterruptible power supply, is a system equipment that connects the battery (mostly lead-acid maintenance-free battery) to the host and converts direct current into mains power through module circuits such as the host inverter. It is mainly used to provide stable and uninterrupted power to a single computer, computer network system or other power electronic equipment such as solenoid valves, pressure transmitters, etc. When the mains input is normal, UPS will stabilize the mains voltage and use it to the load, at this time, the UPS is an AC electric regulator, and it also charges the battery in the machine; When the mains power is interrupted (accidental power outage), UPS immediately converts the direct current energy of the battery to the load through the inverter switching conversion method**220V AC power, so that the load can maintain normal operation and protect the load software and hardware from damage.

UPS equipment is often protected against either too high or too low voltage.

UPS Power Features:

UPS power supply function description:

UPS power supply can be said to be an upgraded version of the inverter, which is compatible with the functions of the inverter, and has the main functions of inverter, voltage regulator, charger, uninterruptible power supply and so on; It can provide timely protection for office computers, computer room equipment, servers, and data storage power.

UPS power supply has now been applied to various industries, such as: office, hospital, finance, community monitoring, shopping malls and other power industries, these functions are inverter can not be compared.

1. The inverter power supply is converted from DC (direct current) to AC (alternating current), and the UPS power supply has three modes: bypass mode, mains mode, and battery mode.

2. Generally speaking, the inverter is just a simple converter, and there is no over-thinking impurity. A device that converts direct current into alternating current is called an inverter.

3. The bypass mode of UPS power supply is to directly go through the mains power without passing through the UPS power host, the mains mode is to pass the mains through the rectifier of the machine, the impurities of the mains are too considerate, and then through the inverter of the host, and then output to the equipment for power supply, while the battery mode is through the direct current (battery electricity) through the inverter and then output to the equipment. In this way, the equipment is well protected.

Fourth, the inverter power supply and UPS power supply system are roughly the same in function and principle, and they can achieve the following two functions: 1Provide a way to regulate voltage changes, eliminate all kinds of electrical interference, and provide high-quality power**; 2.

In the event of an AC mains failure, the necessary backup power supply capacity can be guaranteed. The biggest difference between the two is that UPS needs to be equipped with a battery pack, and the backup time is shorter, while the inverter power supply does not need to be equipped with a battery, and can directly use the various levels of voltage DC panels in the communication room, which has a large capacity and can ensure the uninterrupted operation of the network for a long time.

First, the composition is different.

1.Power inverter: consists of an inverter device.

Power supply: main circuit, bypass circuit, battery and other power input circuits, rectifier (REC) for AC DC conversion, inverter (INV) for DC AC conversion, inverter and bypass output switching circuit, energy storage battery.

Second, the use is different.

1.Power inverter: The power inverter is not only suitable for on-board systems, it can be used as long as there is a DC12V power supply, so as to convert DC12V to AC220V AC, bringing convenience to your life.

When the inverter sends out a high and low voltage alarm and turns it off, the red LED light is on, and there is an alarm sound.

Power supply: used in mining, aerospace, industry, communications, national defense, hospitals, computer service terminals, network servers, network equipment, data storage equipment, emergency lighting systems, railways, shipping, transportation, power plants, substations, nuclear power plants, fire safety alarm systems, wireless communication systems, program-controlled switches, mobile communications, solar energy storage and energy conversion equipment, control equipment and emergency protection systems.

Third, the working principle is different.

1.Power inverter: realize DC input and then output AC.

The working principle is the same as that of a switching power supply, but the oscillation frequency is within a certain range. For example, if the frequency is 50Hz, the output is 50Hz AC. An inverter is a device that can change the frequency.

Power supply: The rectifier device adopts thyristor or high-frequency switching rectifier, which has the function of controlling the output amplitude according to the change of the external power supply, so that when the external power supply changes (the change should meet the system requirements), the rectifier voltage with the output amplitude is basically unchanged. The purification function is done by an energy storage battery.

Since the rectifier's interference with the transient pulse cannot be eliminated, there are still interference pulses in the rectified voltage.

The above is the difference between the inverter power supply and the UPS power supply summarized by Chaote, which is a professional UPS power supply brand, in line with the national standard, and the quality is trustworthy.
