A circuit for selectively diminishing the conductive interval of a pulse control circuit during plugging of a d.c. motor drive system. A thyristor is utilized to bypass a portion of an inductive winding in the charge reversal circuit of a commutating capacitor. The voltage on the capacitor then reverses itself in a shorter than normal time to allow a more rapid commutation of a main thyristor. |
