  • Patent number: 10842056
    Abstract: A cooling device has a cooler, a circulator, a semiconductor temperature detection unit, a refrigerant temperature detection unit, an output acquisition unit, and a flow velocity control unit. An output area of a power converter is divided into a first output area equal to and smaller than a threshold and a second output area exceeding the threshold. The flow velocity control unit controls, in the first output area, the flow velocity of the refrigerant to be maintained within a range where the refrigerant in the heat receiving portion is kept in a non-boiling state; and controls, in the second output area, the flow velocity to be maintained within a range where the refrigerant is in the non-boiling state or a nucleate boiling state. The flow velocity in the second output area is equal to or greater than an upper limit value of the flow velocity in the first output area.

  • Patent number: 8861176
    Abstract: An ignition coil device includes a primary coil, a switching member, a secondary coil and a parallel circuit. The primary coil is to be connected to an external power source. The switching member switches an on state and an off state of electric power supply from the power source to the primary coil. The secondary coil generates a voltage that causes spark discharge at a spark plug as the electric power supply from the power source is switched from the on state to the off state by the switching member. The parallel circuit includes a series coil and a resistor. The series coil is connected in series with a conducting section that electrically connects the secondary coil to the spark plug. The resistor is connected to the conducting section in parallel with the series coil and having a fixed electric resistance value.

    Abstract: In a semiconductor module, a high-potential side conductor includes a wide section on which the high-potential side switching element is mounted, a high-potential side terminal coupled with a high potential source, and a narrow section extending from the wide section to the high-potential side terminal in a first direction. The wide section is wider than the narrow section in a second direction perpendicular to the first direction. The wide section has a first side and a second side opposite to the first side in the second direction. A distance between the first side of the wide section and a low-potential side conductor is shorter than a distance between the second side of the wide section and the low-potential side conductor. The narrow section extends from a portion of the wide section closer to the first side than the second side.
