Webutility efficiency of DCside voltage than the sine pulse width modulation- (SPWM). Although the SVPWM has many advantages, it is difficult toimplement. The most difficult factor is calculating the duty cycles for each power switch, as well as determin the vector sector and pulse ing sequence in each switching cycle. Webmultilevel converters, based on the classical SPWM with triangular carriers. Some methods use carrier disposition and others use phase shifting of multiple carrier signals. This common SPWM method is the extension of bi-level SPWM. One reference signal is used to compare to the carriers. The advantage of the method is it is very simple.
