摘要
逆变器并联虽然能提高电源系统的容量、可维护性和可冗余度,但是其主电路设计和控制方法比单台逆变器复杂,基于此,详细综述了逆变器主电路的拓扑结构。在主电路结构中,分别介绍了独立并联系统、交互并联系统、独立直流电源逆变器并联和共用直流电源并联的主电路结构,同时分别介绍了各自的优缺点,针对不同的主电路拓扑电路,介绍了相应的控制方法。对提高工业自动化电源、高端焊接逆变电源系统的稳定性和可靠性具有一定的参考价值。
The parallel of inverter power can improve power system＇s capacity ,maintainability and redundancy ,but design of main circuit and control method is more complex.This paper detailed the analysis of the inverter＇s main circuit with topology.including independent parallel systems,interactive parallel system,independent parallel of DC power inverter and parallel of common DC power,and their advantages and disadvantages.Aim to different topologycal main circuit,this paper introduced the relevant control method, which is of certain guidance for improving the stability and reliability of industrial automatic power and high-end inverter welding power system .
