Abstract :
In this paper, a novel three-phase sinusoidal PWM voltage source inverter (VSI) is proposed. The inverter has an additional arm to the normal PWM three-phase bridge circuit. The additional arm contributes to reduce the ripple in the AC output current. As an example of the application of this VSI, a utility-connected photovoltaic power generation system is shown. In the system, smooth DC current without pulsation is supplied from a PV array, and the VSI provides sinusoidal AC current for domestic loads and the utility line
