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, by using a rectifier voltage computed with a closed expression. The method is simulated using a C language description of the system and its results are later verified on an experimental test rig. The use of an optimum rectifier voltage and the use of Space Vector Modulation (SVM) provides an operation with lower ripple in the current and in the calculated active and reactive power.
