Performance evaluation of a multisource renewable power converter prototype

Abstract

In this paper a multisource renewable energy system simultaneously fed by photovoltaic and thermo-electric generators is proposed. The designed system provides a multi-input power converter which is properly controlled to achieve both output and input control. The output DC bus is regulated to achieve a proper supply of the output energy buffer. On each input port of the power converter a control on the source operating point is applied to achieve the maximum power transfer from each renewable source. Experimental results are shown to test the efficiency of the proposed solution.
