The Development Of The Electronic Switch Control Circuit For A Single Phase Inverter Used In The Photovoltaic System

This research is centered on the design of the electronic switch control circuit for a single phase inverter to generate a sine wave output voltage similar to the network voltage in terms of frequency and value. The design has the advantage of a pure sine wave with low harmonics and low cost. The technique used is the "sinusoidal pulse width modulation" technique generated by the microcontroller. To ensure the accuracy of the designer inverter and the driving circuit, we performed several tests on different AC loads. The proposed inverter model improved the output waveform and reduced the dead time of the control signal to less than 63 microseconds, witch reducing the harmonics. In addition, the results of the practical test were compared with the simulation results and there was a good agreement.
