Implementation of a drive system for dual single-phase induction motor using a five-leg inverter with carrier-based space vector PWM technique

Abstract

This paper presents the implementation of a drive system of a dual single-phase induction motor system with independently closed loop speed control using a five-leg voltage source inverter. Simple closed-loop speed V/f scalar control method and carrier-based space vector PWM (SVPWM) are implemented on dSPACE DS1104. The details of dSPACE configuration and programming are fully given. The experimental results show that the implemented system is able to independently control to keep speed constant for each motor under various operating conditions.
