The 220v power regulator is composed of a voltage regulator circuit, a control circuit, and a servo motor. When the input voltage or load changes, the control circuit samples, compares, amplifying, and then drives the servo motor to rotate, so that the position of the regulator carbon brush changes, and the coil turn ratio is automatically adjusted to maintain the stability of the output voltage. Ac regulators with large capacity also work on the principle of voltage compensation.

220V voltage regulator is composed of contact autoregulator, servo motor, automatic control circuit and so on. When the grid voltage is unstable or the load changes, the automatic sampling control circuit sends a signal and drives the servo motor to adjust the position of the carbon brush of the autoregulator, so that the output voltage is adjusted to the rated value and reaches a stable state.
The principle of household 220v regulated power supply is: when the input mains changes, the control circuit monitors and detects it, and outputs the control signal to the servo motor to adjust the position of the carbon brush on the autoregulator, so as to ensure the stability of the output voltage. With overvoltage, undervoltage protection device, when the output voltage is higher than the rated value, automatically cut off the output voltage protection load.
The principle of 220V is that it converts 220V voltage to low voltage through a transformer, and then the low voltage voltage passes through a series of circuits, and finally the low voltage voltage is converted to a stable voltage of 220V, thus ensuring the normal operation of household appliances.
