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

    【課題】ユーザがイグニッションスイッチをオンした後に、速やかに使用可能な作業機械を提供する。【解決手段】平滑コンデンサ104は、負荷110の入力に接続される。基板電源108は、電源電圧VDDを生成し、プロセッサ106に供給する。主スイッチ122は、電池102と負荷110を結ぶDCバス101の経路上に設けられ、プロセッサ106からの第1制御信号S1に応じてオン、オフが切りかえられる。制御用スイッチ130は、電池102と基板電源108の間に設けられ、イグニッションスイッチ150がオンするとアサートされる第2制御信号S2を受け、第2制御信号S2がアサートされるとオン状態となる。突入電流防止回路140は、イグニッションスイッチ150がオンするとアサートされる第3制御信号S3を受け、第3制御信号S3がアサートされるとオン状態となり、主スイッチ122とは別経路で平滑コンデンサ104を充電する。【選択図】図3
