This paper presents an evaluation study of two pwm techniques applied to a three-phase voltage source inverter supplied by photovoltaic (PV) energy sources. A Pspice-based model of the pv array is developed and tested. The power and currant of the pv array versus the voltage is plotted. Then the pv array is connected to a basic three phase voltage source inverter VSI. Two control techniques are used. The first one is the classic sinusoidal pulse width modulation spwm, which is based on the comparison of two signals, the sinusoidal reference and a triangular carrier. The second one is based on the principle of harmonic elimination. The system is simulated using orcad-pspice, the results are given, discussed and compared based on different performance indices (output quality, thd, frequency).

Aiming at the problem of large magnitude and high frequency of common-mode voltage (CMV) when space vector pulse width modulation (SVPWM) is used in a three-phase motor fed by a two-level voltage source inverter, a common-mode reduction SVPWM (CMRSVPWM) is studied. In this method, six new sectors are obtained by rotating six sectors of conventional SVPWM by 30°. In odd-numbered sectors, only three non-zero vectors with odd subscripts are used for synthesis, while in even-numbered sectors, only three non-zero vectors with even subscripts are used for synthesis. The actuation durations of three non-zero vectors in each switching period in each sector are given. Simulation and experimental results show that, compared with the conventional SVPWM, the CMV magnitude of CMRSVPWM is reduced by 66.67% and the CMV frequency of CMRSVPWM is reduced from the original switching frequency to the triple fundamental frequency. At the same time, the current, torque and speed of the motor are still good.
