PROJECT TITLE :

Resonant–Repetitive Combined Control for Stand-Alone Power Supply Units

ABSTRACT:

This paper investigates a combined resonant–repetitive (RR) management structure for a three-section four-leg dc/ac converter power offer. The RR control configuration consists by a resonant controller tuned at the system basic frequency operating at the side of a plug-in-sort repetitive controller. The resonant half of the control scheme is employed to assure prompt tracking of the inverter output voltage and to realize as quick as potential system response to load variations; to the current purpose, it is tuned at the basic frequency. At the identical time, the resonant controller is ready to stabilize the system without the necessity of any further further controller; the repetitive half of the theme is implemented for the fine regulation at the system harmonic frequencies. The proposed control configuration is used to manage the facility offer output voltage, providing terribly smart tracking of the output voltage reference even within the presence of a nonlinear load. Experimental validation from a 40-kVA converter prototype is presented to validate the operation of the proposed converter and management.
