Six-phase VSI control using 8-bit MCU

Abstract

In this paper a generation of six-phase voltage using six leg synchronous Voltage Source Inverter and a low cost 8-bit Micro-Controlling Unit is investigated. A simple and cost effective Sinusoidal Pulse Width Modulation for controlling sixleg VSI is presented. A simulation on generation of six-phase voltage using SPWM method was investigated. The main advantage of presented SPWM method is the simplicity and low resource requirement for MCU.
