Abstract: In this paper, a non isolated interleaved, dc/dc boost converter with a high efficiency is proposed for using in photovoltaic system applications. For realizing zero voltage soft switching (ZVS), two active clamp circuits are used for each phases of the boost converter. By utilizing a voltage doubler configuration at the converter’s output terminal and connecting the secondary side of coupled inductors in series, high conversion ration can be achieved. The capacitor is also connected in series with output capacitors to transfer leakage energy to the output. Interleaved structure is used in input side to minimize current ripple and reduce magnetic component. So, the converter not only operates with a higher voltage gain, but also is able to operate more efficiently and can be used in photovoltaic (PV) applications.
Keywords: high voltage gain; interleaved DC-DC boost converter; photovoltaic system; soft switching performance.
