Abstract In this paper, phase compensation resonant control scheme is proposed for PWM converters. With the help of the phase compensation principle of repetitive control, the phase compensation principle of resonant control is illustrated and the organic link is build between phase compensation repetitive control and phase compensation resonant control. Compared with phase compensation repetitive controller, phase compensation resonant controller can independently provide required compensation phase at any harmonics to expectably achieve “zero phase” compensation, and the stable range is thus expanded. Moreover, according to the magnitude of each harmonic, the gain of each resonant controller can be correspondingly selected to optimize system performance. An application example of single-phase PWM inverter is provided to systematically demonstrate the effectiveness of the proposed control scheme.
