Abstract

The photovoltaic (PV) module-integrated converter (MIC) system is the key technology for the future distributed production of electricity using solar energy. The PV MIC system offers “plug and play” concept, greatly optimizing the energy yield from the PV module[1-3]. Each PV module has its own power conversion system, generating the maximum power from the PV module. To make the PV MIC system commercially viable, a low-cost and high-efficiency power conversion scheme should be developed. This project proposes a Dual active clamped dc–dc converter with fast dynamic response for low-voltage PV sources. An improved active-clamped dc–dc converter is presented by using a dual active-clamping circuit. The voltage tension at power switches can be reduced at low-voltage side. Also, a modified proportional integral (PI) controller is suggested for fast output voltage control. The performance of the proposed converter is verified using simulation using PSIM software for the output power of 200 watts.
