OPTIMUM DESIGN OF COMMUTATION CIRCUIT IN A THYRISTOR CHOPPER FOR DC MOTOR CONTROL

Expressions for the commutating capacitor voltage and current during the commutation period of the main and auxiliary thyristor in a chopper for a dc motor control system are found. After a successful commutation, a certain amount of energy is "stored" in the circuit components, and for best component utilization this stored energy has to be minimized. The procedure for minimizing stored energy in the commutation circuit results in the selection of optimum values of commutating capacitors and inductors.
