title = "Approach to realize higher power PWM AC controller",
abstract = "AC controllers are widely used in industry in many applications. Recent research has shown that PWM operation of ac controllers offers high performance characteristics. However, PWM controlled ac controllers are plagued with difficulties to commutate inductive load current from one bi-directional switch to another due to finite switch on/off times. This paper proposes a four step switching strategy for repeated on/off operation of bi-directional switches in an ac controller. The proposed approach permits safe transition of inductive load current at all power factors from one bi-directional switch to another even in the presence of source side stray inductance. Results from an experimental proto-type ac controller coupled to an inductive load are also discussed.",
