针对级联式高压整流电路的控制问题,采用多个VIENNA整流器级联构成高压直流系统,设计了主电路拓扑与双闭环控制器,并提出一种多VIENNA整流器电压平衡的协调控制策略。通过仿真试验,验证了双闭环级联型VIENNA高压整流电路的稳定性及其协调控制的正确性。

Focused on the cascade control problems of the VIENNA highvoltage rectifier system, based on the principle of improving system efficiency and reduce the loss, proposed a dualloop cascadetype highvoltage rectifier circuit, established a dualloop controller, and presented a singlephase cascade VIENNA rectifier circuit coordinated control strategy. Simulation results verified the stability and the correctness of coordination control for dualloop cascade VIENNA high voltage rectifier circuit.
