Advanced Rail Clamping PWM Based Space Vector Algorithm for DTC Induction Motor Drive

Abstract

This paper proposes a generalized method to pulse generation using advanced rail clamping pulse width modulation (ARCPWM) sequences. The proposed space vector approach to pulse generation is generalized for various PWM sequences. The present paper considers two advanced PWM sequences viz, 0121 and 7212. The performance of various ARCPWM methods utilizing these two sequences is analyzed on a direct torque controlled (DTC) induction motor drive for a superior steady state response. Comparison of steady state performance of the ARCPWM based DTC drives is made with reference conventional DTC (CDTC), conventional space vector PWM (SVPWM) based DTC drives.

Keywords: ARCPWM (advanced rail clamping pulse width modulation), conventional space vector PWM, ARCPWM, space vector approach, direct torque controlled, total harmonic distortion (THD)
