Abstract:
1. An apparatus for converting power from a bipolar DC source to supply an AC load having plus and minus input terminals, said apparatus comprising: a bipolar DC source having positive and negative monopoles, and corresponding voltage potentials, with respect to a common earth ground or with respect to a neutral point of an AC load, and a DC ground fault interrupt circuit including a means for detecting a fault current in either monopole of the bipolar DC source to earth ground or to a neutral point of the AC load and a means of automatically interrupting the flow of said fault current, said bipolar DC source having a plus and minus terminal for each monopole and where the minus terminal of the positive monopole is connected to earth ground through a first fuse and where the plus terminal of the negative monopole is connected to earth ground through a second fuse and where there is a means of detecting an open first or open second fuse and a means of opening the first, second and third contactors in response to an open fuse being detected.
