Study of Space Vector PWM Algorithm with Entire Modulation Range

Fei Lin

Abstract

On the basis of analyzing the principle of space vector pulse-width over-modulation(SVP- WM),the classical over-modulation algorithm with two modes is simplified,and a new SVPWM algo- rithm with entire modulation range is proposed.Simulation and experimental results show that this al- gorithm is simple,practical,and uses only one algorithm to realize the smooth transition between linear- modulation,over-modulation,and square-wave regions.
