Abstract
A switching system includes a control circuit that receives On-Off signals indicative of a desired operating state of a switch. The control circuit includes an oscillator that generates a first electrical pulse responsive having a first signal characteristic or a second signal characteristic that is determined by the received On-Off signal, which may be related to a frequency or duty cycle of the pulse. A pulse transformer connected to the oscillator receives the first electrical pulse and outputs a second electrical pulse having the same one of the first signal characteristic and the second signal characteristic as the first electrical pulse. A pulse detection circuit in the control circuit receives the second electrical pulse, determines whether the second electrical pulse has the first signal characteristic or the second signal characteristic, and controls transmission of power and control signals to the switch based on this determination.
