Abstract
A method, a controller unit for a bridge rectifier, and a bridge rectifier system are disclosed for detecting a shorted diode in a bridge rectifier. The method can include determining a phase-to-phase voltage between two phase inputs of the bridge rectifier, wherein a phase input is provided between the two series connected diodes of the respective phase, and indicating a shorted diode fault by determining whether the phase-to-phase voltage is zero for more than a commutation time of the bridge rectifier.
