ABSTRACT:
A circuit for pulse heating a line cathode also protects the cathode from voltage and current surges. An adjustable voltage regulator provides a regulated voltage to a pulse generation circuit. The voltage regulator has a control input which is used to control the regulator output. The voltage on the control electrode is controlled by a control circuit which is actuated by a logic circuit. The logic circuit and the pulse generator are responsive to the horizontal synchronization pulses of the display device containing the line cathode.
