Design and Implementation of a Pure Sine Wave Single Phase Inverter for Photovoltaic Applications

This paper aims at developing the control circuit for a single phase inverter which produces a pure sine wave with an output voltage that has the same magnitude and frequency as a grid voltage.A microcontroller, based on an advanced technology to generate a sine wave with fewer harmonics, less cost and a simpler design.The technique used is the sinusoidal pulse width modulation signal (SPWM) which is generated by microcontroller.The designed inverter is tested on various AC loads and is essentially focused upon low power electronic applications such as a lamp, a fan and chargers etc.The proposed model of the inverter can improve the output wave forms of the inverter and the dead time control reduced to 63s.The finished design is simulated in Proteus and PSIM software to ensure output results which is verified practically.
