正弦脉宽调制技术在逆变器中的研究与应用

Research and Application of SPWM Technique in Inverter

分析了应用于逆变电源的三种正弦脉宽调制技术,比较它们的输出电压频谱及开关损耗。最后选择了HPWM控制方式应用于一个实验样机,并给出实验结果。

Three methods are presented with their respective characters in controlling a SPWM inverter. The harmonics of output and switch loss are studied in emphasis. By choosing HPWM, a experimental prototype is implemented to give the experimental analysis.
