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 includes a low voltage controller and a low voltage table correlating step values to pulse widths, the low voltage controller obtaining a desired pulse width and accessing the table to obtain a step value. The low voltage unit transmits the step value to the high voltage unit using a pulse count modulation format. The high voltage unit includes an opto-isolator for receiving the step value from the low voltage controller and a high voltage controller demodulating the step value. In response to the step value, the high voltage controller accesses a high voltage table correlating step values to pulse width to obtain a pulse width, the high voltage controller generating a control pulse in response to the pulse width.
