Abstract

This paper presents a precision voltage control technique of a single phase PWM inverter for a constant voltage and constant frequency(CVCF) applications. The proposed control employes a PLL compensating loop which minimize the steady state error and phase delay. The computer simulation and experiment are carried out for the actual single phase PWM inverter and the results well demonstrate the effectiveness of the proposed control.
