とを特徴とする整流回路。 Connect a series circuit of a chiyoke coil and two switches via a high-frequency filter in parallel with the output of a rectifier that directly rectifies alternating current, and connect a series circuit of a diode and a capacitor in parallel with each switch to create two series connections. It is a step-up chopper circuit, which turns each switch on and off in the same phase at a frequency sufficiently higher than the frequency of the AC power supply, and controls the on/off ratio to make the AC input current into a sine wave shape. rectifier circuit.
