用于双极性直流系统弹性互联的容错型多端口四有源桥变换器

In this article, a fault-tolerant quadruple-transformer quadruple-active-bridge (QT-QAB) converter is proposed for resilient interconnection of bipolar dc systems. During normal operation, the proposed QT-QAB can achieve power balancing at both high-voltage (HV) and low-voltage (LV) bipolar systems. In the event of a monopolar short-circuit fault, the QT-QAB can isolate the faulty pole on the LV s...
