摘要
根据等效面积补偿原理 ,提出一种新型的三相SPWM算法。使调制度M在 1～1 2 7范围时输出电压基波幅值仍保持线性调制关系。而且采用了分段同步调制技术 ,使波形相位精度高 ,对称性好 。
A novel algorithm of three phase Sinusoidal Pulse Width Modulation (SPWM) is presented This algorithm bases on the principle of equivalent area compensation The output latitude of the based waveform still maintains linearity when the modulation ratio in the range of 1～1 27 Additionally, the phasic precision is high and the waveforms is symmetrical
