  • Patent number: 10483869
    Abstract: Embodiments are directed to power conversion circuits including a bypass circuit for bypassing an inrush current limiting resistor. In one embodiment, a power conversion circuit is provided that includes a bridge rectifier, a current limiting resistor, a controllable current switching device, and a driver. The current limiting resistor has a first terminal coupled to an output terminal of the bridge rectifier and a second terminal coupled to an electrical ground. The controllable current switching device has conduction terminals coupled in parallel with respect to the current limiting resistor. The driver is coupled between the first terminal of the current limiting resistor and a control terminal of the current switching device, and the driver controls an operation of the current switching device based on a current through the current limiting resistor.
