  • High Efficiency Cascaded MOSFET Flyback Converter for Generating the Power Supply Voltage for Power Converter Integrated Circuits
    Publication number: 20260058563
    Abstract: A system is provided that includes a diode bridge for rectifying an AC input voltage. A main switching power converter converts a rectified input voltage from the diode bridge into an output voltage. A flyback converter is coupled either to a pre-bridge node or a post-bridge node to receive an input voltage that is converted into a power supply voltage for a controller integrated circuit. The controller integrated circuit regulates both the output voltage and the power supply voltage.

  • Valley and peak detection for switching power converter
    Patent number: 10666152
    Abstract: A switching power converter is provided with a phase-shifting RC network for phase-shifting a divided version of a drain voltage of a power switch transistor into a phase-shifted voltage. A comparator compares the phase-shifted voltage to a DC bias voltage to detect peaks and valleys during resonant oscillations of the drain voltage of the power switch transistor.
