Abstract :
A high efficiency photovoltaic (PV) module integrated converter (MIC) system is proposed. The proposed system consists of a high step-up DC-DC converter and a single-phase full-bridge inverter. The proposed step-up DC-DC converter has a high efficiency and low-profile. An input ripple current reduction control is suggested to reduce the low frequency ripple current generated by the full-bridge inverter. Overall power efficiency of 95% was obtained at 260 W output power for 36 V PV voltage with ripple current within 3% of the rated input current.
