Abstract
The single-phase stand-alone photovoltaic inverter commonly connects to series of photovoltaic panels for increasing higher voltage dc. This paper presents a design of boost converter connected with a photovoltaic panel anduse this circuit connects in series to increase higher voltage dc source for inverter’s input. The boost converter using PI controller with dspic30f1010 microcontroller is designed to maintain the constant output voltage. Results found that the proposed system can provide 100V constant output voltages for the 20-40 V photovoltaic input voltages according to the different solar irradiance variations. The circuit is connected with four circuits in series in order to provide constant dc of 400 V for the inverter that has ac output of 223 V using with 0.3 kW induction motor loads. The overall efficiency of four circuits is approximately 94.27%.
