  • LLC power converter and switching method thereof
    Patent number: 10135348
    Abstract: In some embodiments, an inductor-inductor-capacitor (LLC) converter includes a transformer having a primary winding, a secondary winding, and an auxiliary winding. The primary winding is coupled to a primary side circuit and the auxiliary winding has a first winding portion coupled between a first terminal and a middle terminal, and a second winding portion coupled between the middle terminal and a second terminal. The LLC converter further includes a first diode coupled between the first terminal and a first node, a second diode coupled between the second terminal and the first node, and a switch coupled between the first node and a reference voltage terminal. The middle terminal of the auxiliary winding is coupled to the reference voltage terminal.
