Abstract :
In this paper, a new control technique for a single-phase AC power supply system is presented. By synchronizing the AC output with the DC bus ripple, only a very small DC bus capacitor is required. This improves the power factor and the quality of the input current. In addition, a simple voltage integral control technique is introduced to control the PWM inverter. The performance of the system is analyzed and results are verified through experimental setup
