摘要
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 high-voltage rectifier system, based on the principle of improving system efficiency and reduce the loss, proposed a dual-loop cascade-type high-voltage rectifier circuit, established a dual-loop controller, and presented a single-phase cascade VIENNA rectifier circuit coordinated control strategy. Simulation results verified the stability and the correctness of coordination control for dual-loop cascade VIENNA high voltage rectifier circuit.
