The objective of this paper is to propose a series-parallel resonant high frequency inverter for stand-alone hybrid photovoltaic (PV)/wind power system in order to simplify the power system and reduce the cost. The proposed inverter consists of two power stages: a DC/DC resonant converter as the input stage and a full bridge DC/AC inverter as the output stage. The input converter is operated with phase shift control, which guarantees zero current switching for most power range. This resonant converter generates a high DC voltage, which is conditioned by the DC/AC inverter to generate the desired low frequency output voltage. The DC/AC inverter is controlled using a pulse width modulation strategy. Simulation and experimental results are given to verify the system's efficiency and have shown the performance of the proposed inverter with desired features. © 2011 Published by Elsevier Ltd.
