Modeling of PV array for DC-DC flyback converter with asymmetrical output voltage

Abstract

This paper manages the modeling of PV(Photovoltaic) array for Flyback converter (FBC) with Asymmetrical voltage. The Solar PV system is fed with Flyback converter on transformer in primary side. The MOSFET switch is controlled by using Maximum power tracing system with the switching frequency of 65KHz. The Petrub and Observe algorithm is utilized in the system for controlling the switch in the converter. The Output of Flyback converter with four different asymmetrical output voltage. The input FBC is 24V and output FBC is 6.3 Vdc,12.6 Vdc,26.2 Vdc and 52.4 Vdc respectively. The output capacitor is used for filter the pure DC output voltage of this system. The asymmetrical output voltage is used for Asymmetrical multilevel inverter. The system is design in MATLAB and overall system is implemented in real time system suing ARDUINO Controller, MOSFET driver circuit and ferrate core transformer.
