    Abstract: A ground fault detection circuit comprising a fuse and a fuse detect circuit. The fuse and the fuse detect circuit are arranged to be coupled in parallel between a reference point and a second point of a monitored circuit for which ground faults are to be detected. The fuse detect circuit is further arranged to detect a fuse break indicative of a ground fault condition and disable at least a portion of the monitored circuit.

    Abstract: An apparatus for producing a compensated voltage output comprising: a first power source or power sink coupled between a first node and a reference node; a second power source or power sink coupled between a second node and the reference node; a biasing means comprising one portion coupled between the first node and the reference node, and another portion coupled between the first node and the second node. The biasing means is operable to generate a controllable bias voltage of either polarity between the first and second nodes to produce the compensated voltage output.
