  • Variable resonant power converter with tunable inductor
    Patent number: 11437923
    Abstract: An electronic power converter is configured to receive power from a power source. The power operates at a switching frequency. The electronic power converter includes a resonant tank circuit operatively connected to the power converter. The resonant tank circuit operates at a tank resonant frequency. The electronic power converter includes a controller operatively connected to the resonant tank circuit. The electronic power converter further includes a variable inductor operatively connected to the resonant tank circuit. The variable inductor is configured to modify the tank resonant frequency to match the switching frequency within a predetermined margin.

  • Multi-output power supply with dual power-on control
    Patent number: 11233450
    Abstract: According to an aspect, a power supply is provided. The power supply includes a plurality of voltage converters including a first voltage converter and one or more other voltage converters. The power supply also includes a power supply control configured to perform a plurality of operations including enabling the first voltage converter during a start-up mode of operation, monitoring and regulating an output of the first voltage converter, reconfiguring the power supply control to enable the one or more other voltage converters based on determining that the output of the first voltage converter meets a regulation threshold, and transitioning from the start-up mode of operation to a regular mode of operation based on enabling the one or more other voltage converters to output one or more regulated voltages by the power supply.
