Title: Rush current limiting circuit
Inventor: SATO TOMOKATSU
IPC: H02M7/06
Filed: 1986-10-08
Abstract: PURPOSE:To ensure stable limit of a rush current in simple constitution by controlling a feeder transistor via a constant current source and therefore reducing the using conditions. CONSTITUTION:The voltage of a power supply 1 is applied to a rush current limiting circuit 4 via a rectifier 3 of an AVR 2. The base of a transistor TR Q2 of the circuit 4 is controlled by the constant voltage obtained by a resistance R1 and a constant voltage diode ZD1 and forms a constant voltage source. Then the base of a TR Q1 connected to the single side of a feeder undergoes the control of constant voltage. Thus the rush current to be supplied to a capacitor C and a CAVR internal circuit 5 is limited. The rush current has no fluctuation due to the using conditions with use of a circuit using a transistor instead of a thyristor. Then the limit of the using condition is reduced. Thus it is possible to limit stably a rush current in a simple constitution.
