CONTROL APPARATUS HAVING FULL CURRENT PULSE LOAD CONDUCTION

Control apparatus for connection with a pulsating current source and to control current flow to a load. The control apparatus consists of a sensing circuit including a first gate operated switch means for controlling current flow through resistance means in the bridge to create a voltage drop thereacross. A control circuit is included which has a controlled switch means for controlling the current to the controlled load. The controlled switch means includes a gate responsive to a predetermined current level to render such control switch means conductive to complete the circuit through the load. Current storage means is connected across the resistance means and with the gate of the controlled switch for storage of current during current pulses in the bridge circuit for subsequent delivery to the controlled switch gate to trigger such controlled switch during subsequent pulses. Consequently, the controlled switch means will be rendered conductive early in each pulse of current to conduct substantially full current pulses to the load.
