A multi-input power converter for hybrid renewable energy generation system

Abstract

This paper studies the dc power supply system to combine with the hybrid renewable energy sources. A multi-input power converter (MIPC) which operates in four types: an operation type wherein power is delivered to dc Bus from hybrid renewable energy sources; a single type wherein only one renewable energy source supplies power to the dc Bus; an inverter type wherein power is delivered to dc Bus from ac grid via inverter module, and a battery type wherein power is delivered to dc Bus from batteries without renewable energy source. In this paper, the integration of the dc Bus and a hybrid renewable power supply system is proposed. A hybrid renewable power energy which integrates the solar energy, wind-power, and city power, etc will be exploited to supply the household appliance and loads.
