摘要
从分析功率因数补偿方法入手,提出三相共补开关拓扑结构及其电路模型,分析投切过程冲击电流形成机理及其避免对策。给出系统硬件主要电路图、设计要点及软件流程图。样机测试结果表明,设计符合要求。
Based on analysis on the power factor compensation,the three-phase common-complementary switch topology and its circuit model,as well as the formation mechanism of impulse current and the method to avoid were proposed.The main circuit of the hardware in the system,the design essentials and the software flow charts were given.The sample testing results indicated that the design met the requirement.
