Redundant and Fault-tolerant Method for Medium Voltage Transformerless PCS
Dan Li, Guanjun Li · 2018
According to demands for highly reliable energy storage converter system, a modular medium voltage transformerless structure with redundant fault-tolerance is designed, which specifies its treatment procedure of redundant tolerance faults. The reliability and redundant fault-tolerance of the modular system is analyzed. Simulation and experiment results show that the system can satisfy the requirement of redundancy and fault-tolerance.
