Abstract
A capacitor-drop power supply includes a rectifier and a rectifier controller. The rectifier is configured to receive an alternating current (AC) signal at an AC voltage and convert the AC signal into a rectified direct current (DC) signal at a rectified voltage. The rectifier includes a first low side switch. The rectifier controller is configured to generate a switch close signal based on the rectified DC signal. The switch close signal is configured to close the first low side switch shunting the AC signal to ground.
