A GTO Cascade Equipment of Saving Energy for Variable Speed Control System

A GTO cascade equipment of saving energy is a modem tyPe of rec-tifire equipment.The Power factor of this equipment is improved greatly. The application of this system will have more important significance for economy of energy. In this Paper the principles and methods of improv-ing the power factor are discussed. Performance curves of the power fac for of a wound-rotor induction motor, a SCR cascade and a GTO cascade equipment are shown also. These Curves are drown from a experime-ntal equipment developed, by us. The comparison between these curves can be used to explain the advantage of the high power factor of a GTO cascade equipment.
