Abstract: An actuator includes a rod, an electric motor to generate a rotational driving force on supply of electricity, an output shaft to output the rotational driving force of the electric motor to the rod, a feed screw mechanism, and a rotation prevention mechanism. The feed screw mechanism includes a female screw portion formed on one of the output shaft and the rod, and a male screw portion formed on the other to mesh with the female screw portion. The rotation prevention mechanism is configured to regulate rotation of the rod caused by the rotational driving force of the electric motor.

Abstract: A charging device for a battery of a vehicle includes an insulation resistance detecting circuit, a charging circuit, a leak current detecting circuit and a decoupling circuit. The insulation resistance detecting circuit includes a coupling capacitor, and is disposed between the battery and a vehicle body for detecting an insulation resistance between the battery and the vehicle body. The charging circuit converts an alternating current supplied from an alternating current source into a direct current and charges the battery in a state without insulting the input terminal and the output terminal and in a state where the vehicle body is coupled to an earth. The leak current detecting circuit detects a leak current between the charging circuit and the earth. The decoupling circuit decouples the insulation resistance detecting circuit from one of the battery and the vehicle body during a charging of the battery.

Abstract: A power conversion apparatus includes: a bridge circuit between AC and DC ends; a converter circuit between the bridge circuit and the DC end; and a control device for the converter circuit. The converter circuit includes: first and second switches in series between terminals of the bridge circuit; third and fourth switches in series between terminals of the DC end; and a reactor between an intermediate point of the first and second switches and an intermediate point of the third and fourth switches. The control device includes: a first controller defining a part of a cycle of an AC voltage as a stop period and stopping switching the first and second switches during the stop period; and a second controller performing voltage/power factor correction controls over an entire cycle by switching the third and/or fourth switches.

Abstract: A battery charger of a battery charging apparatus is disposed on an exterior case of an engine in such a manner that a generated heat is transferred therebetween. An ECU drives a cooling system when an engine temperature and temperature of the battery charger satisfy a predetermined cooling temperature condition. A cooling capacity for cooling the battery charger is improved by establishing a heat radiation passage to radiate a heat from the battery charger efficiently.
