JCIR_V3_N4_RP2 Performance Analysis of Fly-Back Converter Using Photovoltaic Cells Vikash Kumar Rai Krishna Pratap Singh Journal on Circuits And Systems 2322–035X 3 4 20 27 Photovoltaic Cell (PV cells), Fly back Converter, Boost Converter, Inverter, PWM Switching Solar energy systems based on photovoltaic (PV) cells have attracted a considerable interest in recent years due to their free and easily available nature and promise related clean energy. Non-renewable energy resources like coal, nuclear, petroleum gas, diesel, etc., are depleting and hazardous to our environment too. There are two types of converter techniques used in the photovoltaic system, first is the single-stage converter technique and second is the two-stage converter technique. This two-stage converter technique uses photovoltaic cells. In the first stage, a fly-back DC to DC converter is used, while in the second stage, are SPWB based inverter is used. Its performance is discussed and compared with the boost converter based photovoltaic cell, for which MPPT based photovoltaic cells are used. For achieving better performance, a Sinusoidal Pulse Width Modulation (SPWM) technique is also used. September - November 2015 Copyright © 2015 i-manager publications.
