Abstract
In this paper, a single phase effective closed loop control for solar inverter is proposed. As solar irradiance level changes with atmospheric conditions, output of the inverter varies. To maintain the output voltage of the inverter constant a close loop is implemented using PWM technique. A PWM signal is generated by comparing the output of PI controller with two identical triangular signals having a phase difference of 180°. The output voltage is constant within ±0.5% of reference value. The circuit is validated using PSIM software. The simulated AC output waveform has THD within 2%.
