    Abstract: A high voltage power supply for use in a camera system operative with an image intensifier is disclosed wherein the primary of a transformer is energized in response to a voltage derived by horizontal scanning signals, a gain control voltage proportional to the video output of the camera signal and vertical retrace signals so that a high voltage is induced at the secondary of the transformer during only the retrace portion of the vertical scanning signals which has a magnitude proportional to the gain control voltage with this high voltage being translated to the image intensifier.
