초록

The balance of magnetic fux can break and the coupled inductor can be saturated in the case of the switch bridge breakdown of multiphase interleaved inverters. This results in increased coupled-inductor losses, and a decrease in the common-mode inductance, which can further afect the circulation current of the switch bridges, the efciency, and so on. A fault-tolerant strategy for multiphase interleaved inverters based on a short-circuiting coupled inductor was analyzed. By establishing an equivalent magnetic circuit model of the coupled inductor, the magnetic characteristics of the coupled inductor were analyzed. A method to calculate the windings open-circuit voltage, the short-circuit current, and the circulation current of the inverter were established. The proposed method can be used to guide the engineering application design of fault-tolerant operation strategies, such as the device selection and design of coupling inductance. Finally, the correctness of the analysis was verifed by experimental results.
