Abstract
This relates to a rectifier with indicator switch circuit that may be used in a power conversion system. The rectifier with indicator switch circuit may be configured to rectify an ac line voltage and output an indicator signal that is representative of a fault condition in the ac line voltage. The rectifier with indicator switch circuit may include a storage capacitor configured to be charged by the ac line voltage during a first half-cycle of the ac line voltage and a detection capacitor configured to be charged by the storage capacitor during a second half-cycle of the ac line voltage. A switch coupled to the detection capacitor may be configured to generate the indicator signal based on a voltage across the detection capacitor. The indicator signal may be provided to a controller to disable operation of the power conversion system in response to the detection of a fault condition.
