An automotive power regulator, also called an electronic rectifier, electronic regulator. Most products are expressed as stabilizing the voltage of the car's 12V main power supply circuit, improving the power performance of the car, saving fuel, and even some products are directly named as electronic fuel savers.
After the engine is started, the generator is put into operation. Because its output voltage is higher than the maximum voltage of the battery, the battery that was originally in the power supply state is turned into a charged state, and the power supply circuit of the car is guaranteed by the generator. The working conditions of the engine include: idling, shifting, accelerating, decelerating, and cruising, as well as an irregular short-term load of automobile air conditioners. These will affect the engine and cause changes in the speed of the engine, and the corresponding generator speed will also fluctuate.
Unlike the battery, the generator has no power reserve, and its power is instantaneously converted from the kinetic energy of the engine; therefore, any load change in the circuit, regardless of the magnitude of the change and the length of time, must be responded to and borne by the generator. The lag of the generator's power supply response will cause voltage fluctuations, which will make the vehicle's power and handling performance worse.
When the generator is supplying power, because there is no power reserve, the voltage is always fluctuating. The greater the range of the engine's working state, the more severe the voltage fluctuation. This will affect the stability and reliability of the car's work, as well as reduce the reliability of the engine's ignition and the accuracy of the fuel injection volume, thereby affecting the driving performance and overall performance of the car.
After the car is powered by a generator, each system can adapt to its own system, regardless of other electronic control systems; therefore, due to the poor stability of the power supply voltage due to the change of engine speed, it is necessary to equip a voltage stabilizer with a certain power storage capacity in the overall circuit In order to ensure the stable power supply of the whole vehicle and improve the overall stability and reliability of the various electronic systems of the whole vehicle.
There are isolation transformer and voltage regulating transformer inside the voltage stabilizer. The transformer is equivalent to the capacitive effect when starting up. When the voltage regulator is turned on, the instantaneous charging of the transformer and the voltage regulator causes the neutral line to carry current, forming a current loop. If a leakage protector is used at the incoming line, it will act and cut off the input power, causing the regulator to be out of power and unusable.
Therefore, customers please do not use a leakage protector at the input of the voltage stabilizer. If the customer insists on using it, please use a leakage protector at the output of the voltage stabilizer. To ensure the safe use of the voltage stabilizer, the voltage stabilizer must be grounded.
