Abstract :
A novel control technique based on servo control to generate high-quality sinusoidal output voltage for a PWM inverter is presented in this paper. The proposed algorithm can be implemented easily by a digital signal processor because the PWM pattern can be accurately determined at each sampling interval. It provides an excellent voltage regulation, harmonic suppression and fast transient response. Thus, the proposed PWM inverter is very suitable for uninterruptible power supply (UPS). Finally, the computer simulation and experimental results are presented to demonstrate the validity of this technique
