  • Publication number: 20210071721
    Abstract: The present invention relates to a two-speed transmission for an electric driving vehicle and the two-speed transmission for an electric vehicle has only one actuator. The transmission comprises a planetary gear mechanism (12), an elastic body (44), an armature (26) to integrally rotate with an input axis, an electromagnetic coil (46) and a multi-plate friction clutch (30). A ring gear (20) is fixed to a housing. The armature (26) comprises clutch projection portions (26-1). A dog clutch is constituted by the clutch projection portions (26-1) and recess portions (18-2) of a sun gear (18). When the electromagnetic coil (46) is not electrically energized, the dog clutch is engaged. The rotation of the input axis is reduced and is transmitted to an output axis via the sun gear (18) and a carrier (16).

    Abstract: A diode having excellent switching characteristics is provided. A diode includes a silicon carbide substrate, a stop layer, a drift layer, a guard ring, a Schottky electrode, an ohmic electrode, and a surface protecting film. At a measurement temperature of 25° C., a product R•Q of a forward ON resistance R of the diode and response charges Q of the diode satisfies relation of R•Q?0.24×Vblocking2. The ON resistance R is found from forward current-voltage characteristics of the diode. A reverse blocking voltage Vblocking is defined as a reverse voltage which produces breakdown of the diode. The response charges Q are found by integrating a capacitance (C) obtained in reverse capacitance-voltage characteristics of the diode in a range from 0 V to Vblocking.
