Abstract
An on-board battery charger (OBC) includes (i) rail circuits having respective rail controllers and (ii) a main controller. The rail controllers sample voltages supplied to their rail circuits and transmit a fault signal to the main controller upon a comparison between a sampled voltage and a threshold being affirmative of an improper voltage condition (overvoltage or undervoltage) of the sampled voltage. The main controller controls all of the rail controllers to stop operation of all of the rail circuits in response to receiving the fault signal from any of the rail controllers. In a variation, the main controller samples the voltages supplied to the rail circuits and stops operation of all of the rail circuits upon a comparison between a sampled voltage and the threshold being affirmative.
