Abstract

At present,traditional Space Vector Pulse Width Modulation (SVPWM ) technique has been widely used in the variable frequency speed control system,but this technique makes the system produce components of high harmonic wave at integer times of switching frequency.Thus inverter produces conducted Electromagnetic Interference (EMI ) and high frequency noise.Faced with these problems,this paper adopts the method which is to add two-state or three-state Markov chain technique to variable frequency speed control system of SVPWM generator to reduce high frequency noise.This method can make amplitude of harmonic components of output current that is produced by inverter of the system effective in reducing and more uniformly distribute in relatively wide frequency range.Through many simulation experiments,this method can effectively reduce amplitude of harmonic components and is more superior than traditional SVPWM technique.
