Abstract

PURPOSE: To prevent a commutation failure from taking place before occurring even for a case of the armature current sharply varying with a condition easy to cause a commutation failure, with a property of quick response provided in the speed control circuit, by such means that prior to a change of the armature current, a firing phase of the thyristor power converter be made to be controlled.
