Abstract
A fault detector for detecting shoot-through conditions in series connected solid state rectifiers (326, 329) of a power inverter (314) is disclosed. A capacitor (311) discharges when a shoot-through occurs and the discharge current is detected by a current transformer (315). An SCR (317) is gated on by the detector to short circuit the DC bus (327, 328) and prevent damage to the solid state rectifiers (326, 329).
