Abstract: <P>PROBLEM TO BE SOLVED: To provide a device and a method for controlling a relay which connects current limiting elements in series to reduce an inrush current flowing through an electric path between a power switch and a power-supply rectifying device and which short-circuits the current limiting elements by a relay contact after the inrush current passes.  <P>SOLUTION: In the standby state, a device for controlling an inrush current suppression circuit controls a first relay coil and a second relay coil, and turns off first and second relay contacts. When a load power supply is closed, the device for controlling the inrush current suppression circuit controls the first relay coil and the second relay coil, turns on the first relay contact first, and turns on the second relay contact after the inrush current passes. The device for controlling the relay for an inrush current limiting circuit not only reduces consumption power but also disables a current to flow through the relay coils because the current is not required to flow through the relay coils in the standby state. Consequently, the relay is not deteriorated, and the lifetime of relay itself can be lengthened.  <P>COPYRIGHT: (C)2009,JPO&INPIT
