<P>PROBLEM TO BE SOLVED: To provide a power supply circuit suppressing electric power conduction interference. <P>SOLUTION: The power supply circuit includes a first and second power circuits, connected in parallel with a power input unit, load includes a first and second loads. The first power circuit includes: a first rectifying unit connected to the power input unit; a permanent power unit connected to the first rectifying unit and connected to a power opening/closing unit; and a first power unit connected to the first load, and the second power circuit includes: a second rectifying unit and the second power unit connected to the second rectifying unit; and the second power unit connected to the second rectifying unit and connected to a second load. The first load and the first power unit are both grounded, the second load and the second power unit are both grounded, thereby the grounded form of the first load and the second load is of non-co-grounded form to suppress mutual electric power conduction interference. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
