摘　　要：以单相电压型逆变器为研究对象,对其电流跟踪控制方式进行深入分析。对三态滞环电流控制方法做了探讨,针对无源负载情况下出现的跟踪失败现象,提出了解决的措施。以开关损耗最低为原则,设计出三态滞环电流跟踪控制方案。仿真结果表明该方案可以有效降低开关损耗,提高逆变器的效率。This paper researches on the object with single-phase voltage converter and does a thorough analysis on its current tracking control modes. Three-level hysteresis-band current control modes have been discussed to propose a solution aims at the phenomenon of tracking failure of passive load. According to the principle of switch loss minimum, we have designed the three-level hysteresis-band current control plan. Simulation results demonstrate that the plan will effectively reduce switching loss consumption and improve the efficiency of converter.
