摘要： A structure for closing an actuator in a magnetically actuated switch assembly, where the actuator includes an armature and a winding, and the switch assembly includes a manual actuation device coupled to one end of the armature and a movable terminal in a vacuum interrupter coupled to an opposite end of the armature. The structure includes commencing a closing operation of the actuator using the manual actuation device to move the armature towards a closed latch position, detecting that the actuator is being manually closed, and energizing the winding to assist moving the armature to the closed latch position when the armature gets to a predetermined distance from the closed latch position.

摘要： An object is to provide a new electronic control unit that can improve detection accuracy of a sense current even in a region where the current value of the sense current is small. Provided is a sense current detection unit including a plurality of sense transistors that have different current flow rates and that are connected to current output transistors controlling a current flowing in a coil load. The current in the sense current detection unit is input to an analog/digital converter, and the current value of the current flowing in the sense current detection unit is converted into a digital value. The current value of the current flowing in the sense current detection unit is increased through a combination or a selection of the plurality of sense transistors of the sense current detection unit in a region where the current value of the main current of the current output transistors is small compared to a region where the current value of the main current is large.
