Title: Rush current preventing circuit for power unit
Inventor: TOYONO YASUNARI
IPC: G05F1/10
Filed: 1998-06-05
Abstract: PROBLEM TO BE SOLVED: To suppress a rush current with simple configuration without lowering efficiency. SOLUTION: When an input power source 1 is turned on and a switching power source circuit 32 is activated by applying a high level voltage to a control terminal 3, first of all, an FET 11 is turned on and a terminal on the side of the FET 11 at a resistor 10 is connected to the ground. As a result, a current flows through a capacitor 9 and the capacitor 9 is gradually charged. Thus, the gate potential of an FET 4 is gradually lowered and the absolute value of a gate/source voltage Vgs is gradually increased with the lapse of time. When the absolute value of this voltage Vgs exceeds a threshold voltage Vtp determined by the characteristics of the FET 4, the FET 4 is turned on and turned into conductive state.  Namely, until the absolute value of the voltage Vgs exceeds the threshold voltage Vtp after start, the FET 4 maintains a non- conductive state so that the generation of the rush current can be prevented.
