摘要：
A fault detection system for a system having a single DC input and a plurality of A/C loads such as an electric or hybrid electric vehicle. A plurality of inverters convert DC to 3 -phase A/C and supply A/C power to a corresponding individual A/C load. Each inverter includes a common mode current transformer and a controller. An individual corresponding common mode current transformer is coupled to the 3 -phase A/C output of the inverter. An individual corresponding controller is coupled to the output of an individual corresponding common mode current transformer and is coupled to an individual corresponding A/C load. Each controller is configured to detect a fault at the individual corresponding A/C load and in the case of detection of a fault at an individual corresponding A/C load, the corresponding controller disables the A/C load.
