This paper presents the interfacing of Solar Photovoltaic (SPV) system which consistPhotovoltaic (PV) panels with the off-grid load. Two types of converters, namely a dc to dc converterand a dc to ac converter are used for the interfacing. A closed loop boost converter is designed usingthe controller and voltage-feedback technique. An error signal is generated by comparing the outputvoltage of the boost converter with reference voltage and this error signal is fed to controller. Inresponse to error signal the controller generates the pulse width modulation (PWM) signal which isused to control the duty cycle of the boost converter so as output voltage can be maintained to a fixedlevel. Thus boost converter step up solar panel voltage to a stable value at output. The output voltageof the boost converter is fed to a sinusoidal pulse width modulation (SPWM) based inverter whichconverts the dc supply into the ac supply to feed any off-grid load. In this paper first design of boostconverter and then relevant MATLAB simulations are presented.
