  • Shunt modulator for high current arc lamp
    Patent number: 4066931
    Abstract: Shunt modulator for high current arc lamp using series-connected voltage source, first transistor switch, inductor, and lamp. Whenever second transistor modulating switch in shunt with lamp is turned off, voltage surge from inductor fires lamp and first switch is turned on. When inductor current exceeds threshold, first switch is turned off and flyback diode provides return path for inductor current.
