  • Bridgeless flyback converter circuit and method of operating thereof
    Patent number: 10148169
    Abstract: A circuit includes a bridgeless flyback converter having a primary side electromagnetically coupled to a secondary side by a transformer, the primary side being devoid of a diode bridge rectifier, an input capacitor coupled to the primary side of the bridgeless flyback converter, an output capacitor coupled to the secondary side of the bridgeless flyback converter, an EMI (electromagnetic interference) filter coupled between an AC input and the input capacitor, and a compensation stage coupled in parallel with the output capacitor and including a storage capacitor. The input capacitor has a capacitance such that the compensation stage filters the AC mains frequency ripple of the AC input from the secondary side. The compensation stage is configured to store energy in the storage capacitor and regulate the voltage across the output capacitor. The bridgeless flyback converter is configured to regulate the voltage across the storage capacitor.
