Power electronic analog voltage regulation is to simulate the process of voltage level adjustment in power system through power electronic components. Commonly used power electronic components include transformers, converters and bridge converters. These components can change the voltage in the power system by adjusting their working parameters.

Specifically, power electronic analog voltage regulation usually adopts closed-loop control mode, that is, the voltage is regulated by feedback control system. Firstly, the system will measure the voltage level in the power grid, and adjust the working parameters of power electronic components according to the set target voltage value, so that the voltage in the system can reach the target value. Then, the system measures the voltage level again, and adjusts the working parameters of power electronic devices again according to the measurement results until the voltage reaches the target value.

Through power electronic analog voltage regulation, the voltage level in the power system can be stabilized and the voltage can meet the requirements, thus ensuring the normal operation of the power system.
