Abstract :
In Photo-Voltaic (PV) systems to increase the conversion efficiency, efficient converters and efficient PWM switching circuits are required. To design efficient converters and PWM switching circuits mathematical models are necessary. In the proposed study, the mathematical model for photovoltaic cell and for buck-boost converter is developed. In the mathematical model, the parasitic elements of switch, inductor, diode and capacitance are considered. The mathematical model for PWM generator is also developed. The models are developed using volt-sec and ampere-sec equations. The mathematical models developed are validated by experimental results.
