Title:
CURRENT-FEEDING CIRCUIT
Document Type and Number:
Japanese Patent JP3455576
Kind Code:
B2
Abstract:
PURPOSE: To obtain a current-feeding circuit that is suited for the throwing connection of a load with a capacitive load component, by operating a closing connection current one-limiting circuit depending on a voltage difference between a load and an energy source using a first control circuit.
CONSTITUTION: A load 10 can be connected to an energy source via a closing connection current one-limiting circuit 11, and the closing connection current one-limiting circuit 11 has a series circuit that consists of a return flow protection diode 17 and a resistor 18. Then, when plug caps 13 and 14 are connected to an energy source 12, a relatively high closing connection current flows depending on the configuration of an electrical load but the closing connection current one-limiting circuit 11 reduces the closing connection current of the load 10 to a low value where no sparks are generated. Also, a first control circuit 21 compares a voltage that is applied to the load 10 with that of the energy source 12 that is generated at the plug cap 14 and transmits a first operation signal 22 to a switch control part 20 when a voltage difference is at the upper part of a specific threshold, thus obtaining a current-feeding circuit that is suited for the closing connection of a load with a capacitance load constituent.
