Method and system for controlling pulse width in a night vision system power system

摘要

A night vision system comprising a power system having a low voltage unit coupled to a high voltage unit; the low voltage unit including a low voltage controller generating a pulse width code; the high voltage unit including an opto-isolator for receiving the pulse width code from the low voltage controller, a high voltage controller operative in response to the pulse width code to generate an output pulse, a pulse shaping module receiving the output pulse and generating a control pulse; and power electronics operative in response to the control pulse.
