  • Patent number: 9030062
    Abstract: A cooling structure of a rotating electric machine includes a rotor core formed of a plurality of electromagnetic steel plates and a resin molding portion molding the rotor core with resin. The rotor core is provided with a through hole passing therethrough in the axial direction of the central axis that is a rotation axis. The rotor core is provided inside the through hole with an oil passage through which oil circulates. The resin molding portion has a cover portion covering the outer peripheral side of the oil passage. This configuration can provide the cooling structure of the rotating electric machine that achieves efficient cooling while suppressing occurrence of energy loss.

  • Patent number: 8311691
    Abstract: An HV-ECU performs a step of detecting an atmospheric pressure, a step of calculating a maximum value of a boost voltage corresponding to the atmospheric pressure by using a map, and a step of setting the maximum value as a system voltage value and controlling a DC/DC converter. Moreover, the HV-ECU may calculate a resistance value of a gate resistance of a switching element corresponding to the atmospheric pressure by using the map and control the gate resistance to achieve the set resistance value.
