"Rectifier circuit" is a circuit that converts AC electric energy into DC electric energy. Most rectifier circuits consist of transformers, main rectifier circuits and filters. It is widely used in DC motor speed regulation, generator excitation regulation, electrolysis, electroplating and other fields. Rectifier circuit usually consists of main circuit, filter and transformer. After 1970s, the main circuit consists of silicon rectifier diode and thyristor. The filter is connected between the main circuit and the load to filter out the AC component in the pulsating DC voltage. Whether the transformer is set or not depends on the specific situation. The function of transformer is to realize the matching between AC input voltage and DC output voltage and the electrical isolation between AC power grid and rectifier circuit.
