Design & Simulation Of High-Performance Photovoltaic Module-Integrated Converter (PV-MIC)

Vikas P. Patil and Mr. .M. M. Ansari


The paper present a single-phase  grid-connected transformer less photovoltaic (PV) module-integrated converter (MIC) based on cascaded quasi-Z- source inverters (qZSI).In this system ,each qZSI module serves as an MIC and is connected to one PV panel .Due to the cascaded structure & qZSI topology ,the proposed MIC features low-voltage gain requirement , single-stage energy conversion ,enhanced reliability & good output power quality. Optimized module design is developed based on the derived qZSI ac equivalent model And power loss analytic model to achieve high efficiency and high power density .A design example of qZSI module is presented for a 225 to 250-Watt PV panel with 22-50 o/p Voltage . The simulation & experimental result which prove the validity of analytical models. The final module prototype design achieves up to high efficiency with 100 kHz switching frequency. The peak efficiency can be further improved with synchronous rectification. Though the transformer less CMI based PV systems can achieve high performance and low cost
