Sinusoidal and Space Vector Pulse Width Modulation (SPWM-SVPWM) techniques have been extensively used to build inverters, which generate AC voltage from DC voltage. The main application of this type of inverters is for variable speed induction motor drives. With the popularity of microprocessors, the implementations of these techniques are being used widely in inverters. This paper describes the procedures for the implementation of these two modulation techniques on a low-cost high speed microcontroller.
