Abstract :
This paper provides a comprehensive mathematical model for an innovative PWM algorithm able to improve the dynamic performance of low-cost induction machine drives through a special control of the switches during the zero-state. This special sequence produces a voltage larger than usual on the load during transients helping the transfer of reactive energy. This idea is extremely simple to implement and provides outstanding results.
