Abstract :
SVPWM (space vector PWM) method is introduced, mathematical expressions of inverter output voltage, load phase voltage and load neutral voltage of SVPWM and SPWM are deduced respectively, harmonic wave characteristics of SVPWM is analyzed. Maximum output fundamental voltage and modulation ration of the two methods are calculated, the similarities and differences are analyzed.
