ABSTRACT:
The invention is a current regulator having a source of electric current, a switch connected in series with the source of electric current, and a load receiving current through the switch from the source of current. Means are provided for sensing the current through the load, and means responsive to the current through the load turn the switch on and off so that the average current through the load has a predetermined value. A filter smooths out the variations in the current. An inductor and a diode serve as the filter. A gate turn on thyristor (GTO) control electrode serves as the load and the current regulator maintains the control current needed to sustain conduction of the GTO. The current regulator is incorporated in an inverter using GTO devices to generate AC drive current for a motor.
