Abstract
Apparatus for controlling a gated power supply of an image intensifier having a micro-channel plate includes a current-to-voltage converter coupled to the micro-channel plate operable to convert a strobing current on the micro-channel plate to a strobing voltage signal, a AC-to-DC converter coupled to the current-to-voltage converter operable to convert the flickering voltage signal to a voltage level signal, and a control circuit coupled to the AC-to-DC converter operable to generate a varying frequency gating control signal in response to the frequency of the strobing current. The gating frequency is gradually changed until the flickering is substantially eliminated.
