<p><P>PROBLEM TO BE SOLVED: To provide a single fault-tolerant separated dual-bus power supply input circuit with less power consumption than any other conventional ones. <P>SOLUTION: One input circuit includes first and second buses constituted to be connected to first and second power supplies, respectively. The first bus includes a first input line and a first return line, and either of the first input line and the first return line includes a first switch. The second bus includes a second input line and a second return line, and either of the second input line and the second return line includes a second switch and a third switch connected in series. The system includes a plurality of power supplies, an electronic device, and an input circuit connecting the electronic device to the power supply. The input circuit includes a plurality of input lines connecting the electronic device to each of the power supplies, and each of the input lines includes the switch connected between the electronic device and each of the power supplies. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
