Arduino based V/f Drive for a Three Phase Induction Motor using Single Phase Supply

Abstract

Induction Motors (IM) are work horse of power industries. Controlling of IM is crucial task in most of the applications. This paper presents implementation of a Variable Frequency Drive (VFD) controller for a three phase induction motor driven by single phase supply on an Arduino platform. The hardware setup involves a rectifier-inverter combination along with a DC link. The present work concentrates on programming the timers of ATMEGA 2560 microcontroller to obtain the required switching pulses. The simulation results of the developed switching control technique with due validation from a hardware setup are presented.
