Title:
CIRCUIT DEVICE FOR CAPACITOR CHARGING
Document Type and Number:
Japanese Patent JPH0928035
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To enable a capacitor charging circuit used for starting voltage feeding to an electric motor to remarkably quickly charge a capacitor so that the delay time in newly switching on the motor can be minimized. SOLUTION: A charging resistor R1 is bridged by a charging circuit 26 which charges a capacitor C with a low resistance. The circuit 26 is provided with a switching means which bridges the resistor R1 . The circuit 26 is also provided with a transistor T2 connected in parallel with the resistor R1 and the emitter of the transistor T2 is connected to a high-potential terminal 10. The collector of the transistor T2 is connected to the capacitor C through a current-limiting resistor R6 .
