The invention discloses an active filter rectification circuit, which includes a rectification link circuit and a DC link circuit. The rectification link circuit includes an input reactance L1, a main power circuit composed of several power elements, a control circuit, and a sampling circuit. The sampling circuit The collected voltage and current data are sent to the control circuit, the control circuit outputs control signals to the main power circuit, and the alternating current is sent to the main power circuit through the input reactance L1, and the main power circuit converts the alternating current into direct current and sends it to Into the DC conversion link circuit, and output after the DC conversion link. The invention has the advantages that the topological structure design is simple, the input power factor requirement can be met, and the output voltage can be adjusted. The system is equivalent to the traditional two-stage structure, which reduces the number of components, improves the conversion efficiency, and does not require an external low-frequency isolation transformer.
