Motors are important actuators these days and the fault issues on it are very important for the economy and safety. This paper proposes a new fault detection and isolation method for motor drive inverter switch and it is applied to the PMSM driver. This method is based on the SVD (Singular Value Decomposition) of closed loop motor control system transfer function in frequency domain. The current command which is the input of the closed system is expressed as the linear combination of the right singular vector of the SVD. The parameter vector which perform the linear combination can be also acquired from the out current with the operation of right singular vector and singular value matrix on it. When fault occurs in inverter switch, the parameter vector acquired from current command is different from the one acquired from the output current. This property enables us to detect the fault in inverter switch. And the proposed method can isolate the fault, which means the group of faulted switch is identified. Through simulation, the validity and usefulness are presented.
