Abstract

This paper proposes modulating functions of a space vector pulse width modulation (SVPWM) technique based on modified sectors for a five-leg voltage source inverter (VSI) fed dual single-phase induction motor system. The modified sectors are used to simplify the modulating functions in a general form. The modulating functions are fully derived, described and implemented on a DS1104 dSPACE controller. The obtained SVPWM signals are applied to a five-leg VSI for driving the two single-phase induction motors to demonstrate its feasibility in motor drive applications. The calculated and measured modulating signal waveforms of the proposed SVPWM are in good agreement. Experimental waveforms of the motor voltages and currents at different operating frequencies are demonstrated and found to be satisfactory.
