    Carrier-based unbalanced phase voltage space vector PWM strategy for asymmetrical parameter type two-phase induction motor drives
    (2009-07-01)

    This paper proposes a space vector pulse width modulation (SVPWM) method based on a carrier providing unbalanced phase voltages for asymmetrical parameter type two-phase induction motor drives using a three-leg voltage source inverter (VSI). The principle is fully described. The proposed space vector equivalent phase leg reference voltages are derived from conventional ones. With the proposed SVPWM method, the output voltages are displaced at 90° with controllable amplitudes. The validity of the proposed method is verified by both calculated and experimental results. © 2009 Elsevier B.V. All rights reserved.

    Realization of a carrier-based unbalanced output space vector PWM strategy using analogue and digital techniques for three-leg voltage source inverter fed two-phase induction motors

    This paper proposes the realization of a carrier-based space vector pulsewidth modulation (SVPWM) method using analogue and digital techniques. This PWM method provides unbalanced phase outputs for a two-phase three-leg voltage source inverter (VSI). The principle is fully described. The proposed space vector equivalent phase leg reference voltages are derived from conventional ones. With the proposed SVPWM method, the amplitude of the unbalanced phase voltages can be easily controlled as required whilst the phase difference angle is kept at 90 degrees. This characteristic is suitable for a control method of an asymmetrical type two-phase induction motor. The validity of the proposed method is verified by both calculated and experimental results under a variation of PWM parameters with resistive-inductive and motor loads in terms of space vector equivalent reference waveforms, current waveforms and space vector trajectories and so on. © 2009 The Institute of Electrical Engineers of Japan.

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

    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.
