This paper introduces a unified control system for universal power quality controller (UPQC) and its digital implementation based on DSP processor. First, the configuration and basic operation principle of the UPQC with a double-converter structure is briefly introduced. Then a unified control method to coordinately control the series converter and the parallel converter simultaneously is proposed. Accordingly, the hardware configuration of the control circuit is determined. The software design and realization is also detailed. Experimental results on a prototype UPQC are provided in the end. It is verified that the proposed control method and control system implementation fully meet the requirement and ensure the good performance of the UPQC.
