本發明係關於一種高功因推挽式轉換器,其包含有一輸入電源電路、一主動式功因修正電路及一變壓器,該主動式功因修正電路係與該輸入電源電路電性連接,且包含有二電感、一電容、二功率開關及四個二極體,該二功率開關切換該二電感及該電容之儲能釋能,該變壓器之一次側係與該主動式功因修正電路的電容連接及該二功率開關連接,以於該二功率開關開閉時,使該電容與其一次側構成迴路,再由變壓器二次側提供負載電源;藉此,可簡化電路、降低成本、減小體積,並可提升轉換效率,且適用於較大功率電路。 The invention is a high power factor push-pull converter includes an input power supply circuit, active power factor correction circuit and transformer .Active power factor correction circuit connects with input power supply circuit. it contains two inductor, capacitor, two power switches and four diodes. Two power switches control two inductors and capacitors which is storage energy and release energy. The primary transformer connect with capacitor of active power factor correction circuit and two power switches .Circuit is formed with primary transformer and capacitor when two power switch switching, and then load is supplied by the secondary side of the transformer. The above method can achieved simplifying the circuit, reduce costs, reduce the volume, improve efficiency, and high-power circuits.
