Abstract

The proposed, small power, mixed wind and PV energy conversion system (MWPV) consists of a dual input hybrid buck L/ hybrid buck C, DC-DC converter (HBLC), made by two hybrid step down converters with a high ratio of the input/output voltage (the main part), a battery bank as a storage element, and a DC-AC inverter for AC loads supplied with, or without grid connection. The MWPV is coordinated by an energy management control unit (EMCU) in order to obtain maximum energy conversion efficiency and to establish the working regime. Operating modes, analytical description and digital simulations, validated by experimental results, are presented for HBLC. The operation strategy flowcharts of the proposed MWPV are also described.
