<P>PROBLEM TO BE SOLVED: To provide a rush current prevention circuit capable of preventing rush current without using a relay circuit having a high withstanding current/voltage or a resistor having a large withstanding power to perform prompt boosting to a standard voltage of an electronic circuit, and preventing even a rush current caused by a connection (changeover) error of a relay circuit. <P>SOLUTION: This rush current prevention circuit has a first relay circuit RL<SB>1</SB>, a second relay circuit RL<SB>2</SB>, and a current restriction means 1 suppressing a current capacity. The three elements are wire-connected in a Y shape, and an output signal of the first relay circuit RL<SB>1</SB>becomes an opportunity to bring the second relay circuit RL<SB>2</SB>into a conductive state. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
