Abstract

This paper investigates a combined resonant–repetitive (RR) control structure for a three-phase four-leg DC/AC converter power supply. The RR control configuration is com-posed by a resonant controller tuned at the system fundamental frequency working in conjunction with a plug-in-type repetitive controller. The resonant part of the control scheme is used to as-sure prompt tracking of the inverter output voltage and to achieve as fast as possible system response to load variations; to this pur-pose, it is tuned at the fundamental frequency. At the same time,the resonant controller is able to stabilize the system without the necessity of any further additional controller; the repetitive part of the scheme is implemented for the fine regulation at the system harmonic frequencies. The proposed control configuration is used to regulate the power supply output voltage, providing very good tracking of the output voltage reference even in the presence of anon linear load. Experimental validation from a 40-kVA converter prototype is presented to validate the operation of the proposed converter and control.
