Abstract :
The minimum pulse width constraint for the pulse width modulation (PWM) signals of the main devices in load side soft-switching inverters leads to more harmonic distortion of load current and the limited voltage conversion ratio. To alleviate these problems, a space vector modulation (SVM) scheme achieving the maximum pulse width (MPW) is presented using a simple graphic method. Theoretical analysis, simulation and experimental results are presented to verify the effectiveness of the new MPW SVM scheme
