摘要
针对离网型的Z源逆变器提出了一种利用直通零矢量对Z源电容电压进行闭环控制方案.介绍了Z源逆变器的概念,并在此基础上介绍了利用直通零矢量对Z源电容电压进行闭环控制的原理,同时给出了完整的控制框图与PI参数的整定方法.仿真结果表明了控制方法的正确性与有效性.
A close-loop control method was provided to control capacitor voltage for off-line Z source inverter using the shoot-through state.First of all,The concept of Z source inverter was introduced.Based on the concept,the close-loop control method was provided to control capacitor voltage using the shoot-through state.Furthermore,the whole control block diagram and the method was given to get the PI parameter.Finally,the simulation results proved that the accuracy of the controller.
