FULL-BRIDGE POWER CONVERTER

Abstract: a full-bridge power converter is provided. the full-bridge power converter includes a transformer circuit, an input-side circuit, an output-side circuit, and a controller. the input-side circuit includes an input-side full-bridge circuit and an input inductor. the input-side full-bridge circuit includes multiple power switches. the input inductor is coupled between a positive power terminal of the battery module and the input-side full-bridge circuit. the output-side circuit includes an output-side full-bridge circuit and an output capacitor. the controller turns on the power switches during a first period, causing the transformer circuit to release an electric energy stored in the transformer circuit. the controller turns on the power switches during a second period after the first period, and controls the output-side full-bridge circuit to precharge the output-side full-bridge circuit by using an energy stored in the output capacitor.
