A Simple Switch Selection State for SVM Direct Power Control

Abstract

This work presents a simple scheme for vector selection in direct power control (DPC) in a three-phase rectifier without the use of switch selection tables. The method is simulated using a C language description of the system and its results are later verified on an experimental test rig. Additional states are obtained using space vector modulation (SVM) which reduce the hysteresis band of the active and reactive power controller
