Abstract:
1. A power supply for converting alternating current to direct current, said power supply comprising: at least one first terminal for receiving alternating current; at least one neutral point electrically neutral with respect to said at least one first terminal; at least one second terminal for outputting direct current; at least one grounding point serving as the electrical ground for said at least one second terminal; a bridge including plurality of diodes configured between said at least one first terminal, said at least one neutral point, said at least one second terminal, and said at least one grounding point to full-wave rectify said alternating current; and a voltage controlled switch for switching off a portion of said bridge in the event that a voltage threshold is exceeded, said switch having an input, a first output, and a second output, said input and said first output connected in series with at least one of said plurality of diodes, and said second output connected to at least one of said at least one first terminal, said at least one neutral point, said at least one second terminal, and said at least one grounding point, wherein said voltage controlled switch further comprises:
