Power converter having high efficiency at low load

摘要: A power converter includes a DC source, transformer having first winding, MOSET and PWM controller at the primary side second drive control unit, current detection comparator MOSFET secondary side. The has its input end electrically connected to unit output which is for synchronous rectification. one of body diode built therein. winding constitute combination circuit load that capacitor thereto in parallel manner. By means aforesaid arrangement, conduction loss low minimized, thereby improving efficiency load.
