Abstract
A single-phase photovoltaic inverter presents a double line frequency voltage ripple which means it needs a bulky capacitor for reducing this issue, however, it causes power density decreases. The approach of this paper is to obtain high conversion efficiency, using film capacitors instead of the electrolytic capacitors in order to minimize double-line-frequency voltage ripple. Proper operation of the proposed topology has been corroborated through simulation results, showing that the injection of photovoltaic power to the grid and attenuated dc-link voltage ripple are carried out simultaneously.
