Abstract:
the aim of this paper is to improve efficiency andstability of first stage DC-DC converter in Photovoltaic (PV)power generation systems. In PV systems it is crucially importantto have DC-DC converter with high efficiency, high step up ratio,low ripple in input current and output voltage. Definitely thesecriteria remind researchers of the interleaved boost converters.Robustness, stability, cost, size and weight are vital parametersusually are neglected in researches which has been done in thisarea. In this paper with regarding to above mentioned features forDC-DC converters a zero voltage switching (ZVS) method for IBChas been proposed. Proposed ZVS circuit does not containauxiliary switches and has very simple structure. Reducingswitching losses, increase efficiency of IBC also switchingfrequency can be increased which lead toward smaller weight andsize. In order to avoid instability of converter, providing turn-onZCS condition and decreasing ripple of input current and outputvoltage three boost converter has been interleaved and operate inDCM. As result by using proposed method higher power rate andhigher efficiency are achieved. 0.5Kw IBC is simulated to verifythe effectiveness of proposed method.
