摘要
在分析电压空间矢量调制(SVPWM)基本原理的基础上,证明了SVPWM具有最大的直流电压利用率。将SVPWM和常规SPWM进行了对照和分析。提出了一种与SVPWM等效的改进SPWM调制方法。另外,提出了一种与低开关损耗SPWM相对应的SVPWM实现方法,使开关损耗降低了33%。
By analyzing the basic principle of voltage space vector pulse width modulation(SVPWM),it is proved that the dc voltage utilization ratio of SVPWM is the highest. SVPWM is Compared to conventional SPWM.A modified SPWM which has the exactly same effect as SVPWM is presented.A new realizing method of SVPWM corresponding to SPWM with low switching losses is advanced,Which reduces the switching loss by 33%.
