摘要
输入串联输出并联逆变器组合系统适用于高压直流输入、大电流交流输出的应用场合,其多模块串并联组合的特点令其可有效提高系统工作的可靠性。为了切实体现这一优点,需实现该系统的冗余运行,这实际上包含2个步骤:实现系统的分布式控制;实现其冗余功能。首先给出一种新的分布式架构及控制策略实现模块间功率均衡,讨论控制环路间的关系并进行设计;在实现分布式控制的基础上提出一种可保证系统冗余运行的控制方案,并给出热插拔时序;最后研制3模块的原理样机,实验结果验证了所提方案的正确性和有效性。
The input-series-output-parallel（ISOP） inverter system is very suitable for high input voltage and high output current power conversion applications. Its characteristics of multi-module series-parallel combination can significantly improve the reliability of the operation. To highlight the advantage, we should execute the redundancy, which covers two steps： implementing distributed control, and then actualizing the redundant function. This paper firstly put forward a new solution dedicated to distributed configuration and its control strategy. The relationship between the control loops was analyzed and their parameters were designed. Then a novel method to achieve redundancy was proposed based on the distributed control. Also the timing sequence was provided. At last, a three-module prototype was built and the experimental results validate the effectiveness of the above strategy.
