ABSTRACT:
A low level current travels from a source through the high voltage cable from the remote end to the local end of the cable in a pulse power circuit. The current is detected, and a signal is generated by a bias sensing circuit. If the low level current is not positively detected, no pulse is allowed to occur, preventing accidental damage and high voltage hazard. In some embodiments, the current is coupled to ground at the local end through an isolation inductor, commonly a secondary winding of a high voltage pulse transformer. The low level current then passes through a shunt resistor from ground to an input terminal of the source, thus completing the circuit and generating a voltage between the source input terminal and ground that confirms continuity of the circuit through the high voltage cable.
