Comparison of current controllers for 3-phase UPS based on multiloop control strategy

This paper deals with the basic options of suitable control method for power structure operating in island mode. A brief description of power structure and its utilization possibilities is presented. The simulation of selected control method and power structure was created in Matlab/Simulink for verification the proper function of control method and for comparison the properties of selected controllers. The control algorithm was implemented on TMS320F28335 digital signal processor (DSP) and at first debugged on the laboratory prototype and then applied to a real system. The Experimental results are presented and can be compared with simulation results.
