Basic block diagram of switching rectifier

The switching rectifier mainly consists of 4 parts: input loop, power converter, rectifier filter circuit and control circuit, as shown in the figure. The input circuit rectifies and filters the AC input voltage into a relatively flat high-voltage DC voltage, converts it into a high-frequency pulse voltage through the power converter, and then converts the high-frequency pulse voltage into a stable DC voltage through the rectifier and filter circuit, and outputs it to the load. . The function of the control circuit is to ensure the stability and adjustability of the output DC voltage.
