How to choose a voltage regulator How to choose a voltage regulator?

The voltage regulator is to play a role in voltage stabilization!

UPS itself also has a voltage stabilizing effect!

There are 2 types of UPS.

1. Back-up UPS, direct supply to mains! After a power outage he took over.

I recommend buying a **-type UPS nose on it! There is no need to buy a battery. In this way, it can play a role in voltage stabilization! If you want to supply power when the power goes out in the future, just buy a few more batteries and install them! No waste of resources at all!

The first two said it well, hehe.

In switching regulators and switching capacitive converters, an internal oscillator is used to set the switching frequency of the output transistor. The value of this switching frequency can determine some of the external components used in the converter, determine the frequency of noise generated by the converter, and affect the performance of the converter.

Some converters allow the switching frequency to be changed by adjusting the frequency of the internal ** ("frequency regulation") or by synchronizing the oscillator with an external power supply ("sync").

By increasing the switching frequency, smaller components (capacitors, inductors) can be used in the converter output stage. This can reduce the efficiency of the converter by increasing switching losses unless higher quality components are used at the same time.

The voltage regulator has a large AC voltage regulator of tens to thousands of kilowatts, which is a working power supply for large-scale experimental, industrial and medical equipment. There are also small AC regulators ranging from a few watts to several kilowatts, which are designed to provide high-quality power for small laboratory or home appliances.

According to the different output properties of voltage regulators, voltage regulators are generally divided into two categories: AC voltage regulators (AC stabilized power supply) and DC voltage regulators (DC regulated power supply). The following focuses on DC regulated power supply, referred to as regulated power supply.

According to the working state of the adjustment tube, the regulated power supply is often divided into two categories: linear regulated power supply and switching regulated power supply. In addition, there is a small power supply that uses a regulator tube.

The input of the regulator is terminated with a 220 power supply, and the output is terminated with an electrical appliance.

Connect the input of the voltage regulator to your mains power, and the output to the electrical equipment, and turn on the voltage regulator switch. It should be noted that some voltage regulators have an output of 110V, which is for those imported equipment or equipment that needs 110V power supply.

When choosing a voltage regulator, consider what standby loads the regulator needs to be connected to, and what is the total power.

Add up the total power to be loaded to get the sum to get the minimum output power of the regulator. Calculate the standby power: Calculating the standby power is actually relatively simple, directly look at the product parameters on the product identification plate, and take the maximum power.

The maximum power value of each power unit to be loaded is taken and then the power is added together to calculate the minimum power value of the voltage regulator. When selecting a voltage regulator, we add a certain amount of idle power to the voltage regulator for later expansion, and it should be started at the same time as the load.

1. Capacity safety factor. The AC regulated power supply is based on the output apparent power as the nominal rated capacity, and under normal circumstances, the load is not pure resistivity, that is, the power factor, and the active power that the regulator can actually output. Therefore, in the actual selection, the regulated power supply should be reasonably selected according to the specific conditions such as rated power, power factor and load type of the electrical equipment, and the output power should be left with an appropriate margin, especially when the impact load is selected, the margin should be larger.

2. The output capacity curve of the uncompensated regulated power supply. When the input phase voltage of the auto-coupling regulator is lower than 198V, the output capacity begins to decrease; When the input phase voltage is equal to 160V, it drops to 50% of the rated capacity of the regulator. Therefore, special attention should be paid to reducing load derating at the low end of the power supply voltage, so as not to overload the regulator and burn out.

The auto-coupling regulator is capable of outputting both 220V and 110V voltages simultaneously. The computer should use a servo regulator or other non-intermittent power supply regulator.
