Abstract:
A dual switches Flyback power converter with a wide input voltage range according to the present invention comprises an input diode and an energy-storage capacitor. The input diode can prevent the reflected voltage from the power transformer of the power converter to charge the electrolytic capacitor of the power converter. The energy-storage capacitor will store the reflected voltage and the energy of the leakage inductor of the power transformer. The energy stored in the energy-storage capacitor will be recycled to the output voltage of the power converter. Further, the input diode can be replaced by an input transistor to prevent the reflected voltage from the power transformer to charge the electrolytic capacitor.
