Abstract

See full text

The present disclosure provides step-down rectifier circuit includes a rectifier module, a charge pump module, a filter unit, and a control unit. The rectifier module includes a first bridge arm unit connected to in-phase output terminal of an alternating current signal and a second bridge arm unit connected to out-of-phase output terminal of the alternating current signal. The charge pump module includes a first voltage converter unit and a second voltage converter unit in parallel. The control unit is configured to output a first pulse width modulation signal to control the on and off of the switch transistors in the rectifier module, and output a second pulse width modulation signal to control the on and off of the switch transistors in the charge pump module, such that an operating frequency of the charge pump module is a positive integer multiple of the frequency of the alternating current signal.
