摘要：
Fault tolerant an important role in improving reliability and availability for permanent magnet synchronous generator (PMSG) wind turbines. The open-circuit (OC) faults in the machine side converter (MSC) interrupt the input AC current, which cause harmonics and DC-link voltage ripple. In this paper, the OC fault of a switch of insulated-gate bipolar transistors (IGBTs) in MSC was examined by changing the SVPWM switching pattern. In addition, the technique of fault tolerant was performed without the need for additional hardware and complex calculations. The validity of this paper is verified by MATLAB simulation results.
