The random control of space voltage vector PWM based on regular sampling

Xue Zhao-wu

Abstract

A random control of space voltage vector PWM based on regular sampling for three-phase voltage source inverter is described.This paper illustrates a fast algorithm of SVPWM in the less switching loss mode. It uses DSP numerical controller to change the positions of zero voltage vectors randomly, and then two less switching loss modes are selected randomly, which make harmonic that come from inverter distribute evenly.
