OPERATING MACHINE
Document Type and Number:
Japanese Patent JP2016101061
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an operating machine which can be immediately enabled after a user turns on an ignition switch.SOLUTION: An operating machine comprises: a smoothing capacitor 104 connected to an input of a load 110; a substrate power supply 108 which generates power supply voltage Vand supplies the power supply voltage Vto a processor 106; a main switch 122 which is provided on a pathway of a DC bus 101 linking a battery 102 and the load 110, and which is switched between ON and OFF depending on a first control signal S1 from the processor 106; a control switch 130 which is provided between the battery 102 and the substrate power supply 108, and receives a second control signal S2 which is asserted when the ignition switch 150 is turned ON, and turned to be an ON-state when the second control signal S2 is asserted; and an inrush current prevention circuit 140 which receives a third control signal S3 asserted when the ignition switch 150 is turned ON, and turned to be an ON-state where the third control signal S3 is asserted, and charges the smoothing capacitor 104 by a separate pathway from the main switch 122.SELECTED DRAWING: Figure 3
