Abstract :
This paper introduces an effort to overcome the zero steady-state errors resulting from the direct use of the conventional PI regulators to AC signal. A novel type AC PI (P+Resonant) regulator based on the theory of carrier-servo control systems that DC regulators are converted into AC regulators is applied to the inverter. Theory analyses and simulations verified the validity of the new regulator and show a better transient performance. The regulators also proved to be applicable to both single-phase and three-phase constant voltage constant frequency (CVCF) inverters.
