AN955, VF Control of 3-Phase Induction Motor …
2005 Microchip Technology 1AN955 INTRODUCTIONVF Control using the Sine PWM algorithm is a popularalgorithm for AC Induction Motor Control ; however, thisalgorithm has certain drawbacks which affect theoverall system efficiency. A more advanced switchingalgorithm, like Space Vector Modulation (SVM), over-comes the drawbacks of the Sine PWM algorithm andincreases the overall system application note includes the description of theSVM theory and its advantages over the Sine PWM. Italso discusses the SVM digital implementation for VFcontrol using Microchip s PIC18 FXX31 8-bit micro-controllers.
