Power semiconductor loss evaluation in voltage source IGBT converters for three-phase Induction Motor drives

Abstract

This paper addresses the timely issues of power loss calculation methods in the most common voltage source three phase PWM converters (VSC). There are mainly two kinds of power semiconductor losses to be considered, the conduction losses and the switching losses. A reconfigurable Induction Motor (IM) drive is controlled by the conventional PWM and space vector PWM based methods. The power losses will be evaluated with the different control strategies and verified based on the test-bed using a control system rapid prototyping environment such as dSPACE.
