Abstract
A half-bridge flyback power converter is provided. The half-bridge flyback power converter comprises a high-side switch and a low-side switch periodically conducting an input voltage to a primary winding of a transformer. When the high-side switch and the low-side switch are switched off, energy stored in the transformer is transmitted to a secondary circuit and serves to charge a bulk capacitor. A forward diode facilitates to combine the input voltage with a voltage across the bulk capacitor for powering the secondary circuit. Therefore, the power consumption of the leakage inductance is reduced and circuit topology is simplified.
