12V DC to 6V DC 24V to 12V is the easiest way?

When the current is not large, these devices can be used to form a simple linear regulated power supply. If you draw a schematic, the parameters are not necessarily correct. Of course, if you don't need those components of yours, you can just use an LM7806.

In the case of AC, a rectifier diode is inserted into the circuit to reduce half a cycle, which is 6 volts. In the case of DC, it can be stabilized to 6 volts with a DC regulator.

Looking at the market, the vast majority of batteries used in children's electric vehicles are 6V, and the capacity is generally not high, which is 4AH (ampere-hour), and a small number of 7-ampere-hours, so the use time is often not long. 6V large-capacity battery, which is not common on the market (earlier there was a 36V electric car with 6 6V12Ah, but now it is rare).Not very easy to buy.

Many people who are engaged in electric vehicle maintenance will wonder if they can use 12V batteries in children's electric vehicles.

It was proposed to use 7806

It's not a no-no, but it depends on the application. We're talking about the application of children's electric vehicles here. This doesn't quite fit.

Because the maximum output current of the 7806 plus the heat sink is also safe. Electric vehicles consume much more than that. Simply scaling up also won't work.

At the very least, it needs perfect over-current protection and short-circuit protection to prevent the circuit from being damaged by high current. But that's not what we're going to talk about today. (Added:.)

The cost is not easy to control, and the power consumption is relatively large. If you want to use this method, it is better to make a PWM pulse width modulation motor control circuit to control the speed of the motor, which is simple and convenient. )

Can I use a Zener diode? It is the easiest to implement with a regulated diode, as shown in the figure below, the most commonly used regulated power supply in the products I developed, there is absolutely no problem, I hope it will help you.

Since the current is not large, the diodes are connected in series until the output is 6V.

The switching voltage regulator module can be used, and the specific linear loss of the switch is small, and the heat generation is low.

with a multimeter. Measure how much resistance of the equipment to use 12V electricity, and then connect a resistance equivalent to the device in series (that is: equipment resistance value = series resistance value), but also consider the current of the equipment, if the current of the 24V power supply is greater than the load current of the equipment, you have to connect a resistance shunt in parallel (resistance value = equipment resistance x2), otherwise even if it drops to 12V, the equipment will be burned.

Method 1: Use a multimeter to measure how much resistance of the device to use 12V electricity, and then connect a resistance equivalent to the device in series (that is: equipment resistance value = series resistance value), but also consider the current of the device, if the current of the 24V power supply is greater than the load current of the equipment, you have to connect a resistor shunt in parallel (resistance value = equipment resistance x2), otherwise even if it drops to 12V, it will burn your equipment.

Method 2: It is very simple to use a piece of 7812 to get it, 7812 only has 3 pins, 1 pin is connected to the input (connected to the 24V positive end), 2 pins are connected to the common end (connected to the 24V negative end, which is also the output negative end), 3 pins output (12V output), note that the maximum output of 7812 is only 1A current, and a large enough heat sink is installed when in use.

Summary. Direct current cannot be rectified or stepped up or down, and frequency conversion is required to reduce voltage. It is also possible to connect a voltage divider in series to step down.

The amount of resistance in series is determined by the amount of current in the line. For example, 2A, a resistor with R=48V 2A=24 ohms can be connected in series.

How do you change 60V DC to 12V voltage?

Direct current cannot be rectified or stepped up or down, and frequency conversion is required to reduce voltage. It is also possible to connect a voltage divider in series to step down. The amount of resistance in series is determined by the amount of current in the line. For example, 2A, a resistor with R=48V 2A=24 ohms can be connected in series.

The simplest way is to connect a 60V DC to an adjustable resistor, from which the required DC voltage can be obtained. The resistance of the adjustable resistor is calculated based on the output current of the required 12V power supply.

Hello, dear, 60V step-down to 12V can not be used for step-down resistor, the resistor is just a current-limiting element, even if two resistors are used to divide the voltage, it can not bring the load, to step down 60V to 12V, you can use DC to DC DC step-down module, input to 0-45V 12A 400W constant current, this step-down module can be used to regulate the voltage, and there is a fixed 60V to 12V can not regulate the voltage used on the battery car.

Connect using an inverter.

DC higher voltage +12V becomes DC lower voltage +5V, it is feasible to use integrated voltage regulator circuit 7805, pay attention to add heat sink, output current to be within.

Note that in order to obtain a stable output voltage, the current flowing through R1 is less than the maximum power consumption of 2W without heat sink, and the maximum power consumption of 200 200 4mm3 heat sink can be reached to protect the diode to prevent the output of the voltage regulator from being damaged by a short circuit and the IC, and VD2 (IN4002) is used to prevent the input from being short-circuited and damaging the integrated circuit.

Summary. Hello, glad for your question. It's more troublesome, or even more than worth the loss, you use four 12V batteries in series, and you can simply have a 48V power supply.

Is it possible to turn 12V DC into 48V DC?

Hello, glad for your question. It's more troublesome, or even more than worth the loss, you use four 12V batteries in series, and you can simply have a 48V power supply.

If you want to change 12V DC to 48V DC, you must first change 12V DC to AC through the switching circuit, then raise the voltage to 48V AC through the transformer, and then rectify the filter to DC 48V or adjust the duty cycle of the switching circuit to get more voltage value. So you don't have to do it this way unless you have to.

What is DC 12V Hello dear, refers to the output as DC, 12V: refers to the output voltage of 12 volts. "Direct current" (DC), also known as "constant current", constant current is a type of direct current, which is a direct current that does not change in size and direction.

Direct current (DC) is the unidirectional flow or movement of electric charges, usually electrons. The current density varies over time, but the direction of movement is usually the same over all times. As an adjective, DC can be used as a reference voltage (its polarity never changes).

Direct current is generated by electrochemical and optical cells and batteries. Conversely, in most countries, the current flowing out of the device is alternating current (AC). Alternating current can be converted to direct current through a power supply consisting of a converter, a rectifier (which prevents the current from flowing in the opposite direction), and a filter (which eliminates the slippage in the current flowing from the rectifier).

Voltage, also known as potential difference or potential difference, is a physical quantity that measures the difference in energy between a unit charge in an electrostatic field due to different potentials. Hope it helps.
