In this study, space vector pulse width modulation (SVPWM) methods for six‐phase asymmetrical ac drives are discussed including continuous and discontinuous switching sequences. These switching sequences are adapted from the carrier‐based PWM techniques. Some additional sequences are also derived which reduce the intricacy of programming algorithm. Total six pulse width modulation (PWM) techniques are selected for simulation and experimentation. The comparative performances of these modulation techniques are studied in terms of harmonic distortion factor (HDF), torque and current ripples and switching losses. Based on study, a new PWM technique termed as 6SVM3‐B2 is found that leads to the lowest HDF and current ripple in prototype model.
