Abstract: A bridge rectifier circuit and a wireless power receiver configured to receive high voltage AC inputs and generate a stable DC voltage without exposing the bridge rectifier circuitry components to damaging high voltages are provided. The example bridge rectifier includes a plurality of rectifying transistors positioned to generate a DC voltage upon receiving an AC current. The example bridge rectifier circuitry further includes voltage control circuitry designed to output an intermediate voltage to a terminal of one or all of the rectifying transistors of the bridge rectifier. The output intermediate voltage prevents a voltage difference across the terminal of the rectifying transistor from exceeding a maximum voltage rating of the rectifying transistor.
