A novel technique for eliminating switching transients of variable reluctance drive inverter / Mohd. Shahrunnizam Sampul

This thesis describes a new method for eliminating switching transients of variable reluctance drive inverter [7]. In standard VR converter, rapid current commutation is achieved by forcing the motor phase current against the supply voltage via a pair of diodes. Hence the commutation diodes tend to...
