煤矿输送机、通风机等设备的变频调速,或者一些滤波器和补偿装置都需要用到整流逆变电路,它们均存在谐波多的问题,为此提出了一种基于相移变压器的三电平48脉冲电压源型逆变器。通过对这种拓扑结构进行了仿真研究,结果表明,该逆变器对谐波有很好的抑制作用,具有优良的工作性能和很高的实际应用价值。%For many of the rectifier inverter circuits harmonic problem was proposed based on the phase shift of transformer three level 48 pulse voltage source type inverter,the inverter is harmonic have very good inhibition,finally to the extension of simulation research on structure,and the result shows that the inverter have excellent work performance instruments,has the very high application value.
