Abstract

See full text

A single-stage AC-DC converter circuit with a power factor correction function. The single-stage AC-DC converter circuit comprises a primary-side AC-DC converter, a transformer, a secondary-side AC-DC converter and a controller which are connected to each other. The primary-side AC-DC converter is configured to convert an AC power source into DC. The secondary-side AC-DC converter is configured to convert electrical energy into DC and supply power to a load. The controller is configured to control duty ratios of power switches in the primary-side and secondary-side AC-DC converters, and a phase difference between control signals for the power switches, and finally control the amount of electrical energy transfer and correct a power factor. The single-stage AC-DC converter circuit of the present invention reduces the capacity and volume of a filter inductor and a voltage stabilizing capacitor, and has the advantages of simple circuit and low cost.
