| Abstract: | The artical probes into two major problems occuring in the wave-generating process of SPWM inveter, the carrier rate, the impacting current in the process of switch and the moduclation to the high output frequency. An effective solution is put forward and under the solution, the fluctuation of the output voltage of inveter stops and the output harmomics is lower. |
