  • Publication number: 20150015303
    Abstract: An impulse voltage generator uses a predetermined rectangular waveform signal and a high voltage to generate an impulse voltage. The high voltage is obtained by boosting an instruction voltage of the rectangular waveform signal on a per-cycle basis. A partial discharge frequency calculation section receives detection signals based on partial discharges occurring in an object to be measured by the application of the impulse voltage and counts the detection signal on a per-cycle basis as a partial discharge frequency. An application voltage signal observation circuit observes an application voltage signal indicating the impulse voltage applied to the object to be measured. In a first cycle in which the partial discharge frequency reaches a specified frequency or more, a voltage value acquiring section sets, as a partial discharge starting voltage, the peak value of the voltage indicated by the application voltage signal output from the application voltage signal observation circuit.

  • Patent number: 8914179
    Abstract: During an inertial energy storage operation, electric power conversion at an inverter is controlled such that a direct current electric power from an electric power storage device is converted into an alternating current by the inverter so as to be supplied to stator windings, such that torque in the direction of engine rotation is applied to an output side rotor from a stator to rotatively drive the output side rotor in a state where power transmission from the output side rotor to a drive axle is stopped. During a cranking operation after the inertial energy storage operation, the electric power conversion at an inverter is controlled to permit application of the alternating current to rotor windings, such that a torque in the direction of engine rotation is applied to an input side rotor from the output side rotor, thereby rotatively driving an input side rotor to crank the engine.

  • Publication number: 20140292382
    Abstract: A signal generator generates a combined signal that is generated only in the period where supply of a pulse signal is effected, a pulse signal whose frequency is of a higher impulse repetition frequency than the frequency of the period setting signal and whose amplitude represents a voltage value that is lower than the high voltage HVDC value. A semiconductor switch accumulates electric charge on a capacitative element by means of the high voltage HVDC from the high voltage generator when the voltage value of the combined signal is lower than the set gate voltage value and generates an impulse voltage whose peak value is the value of the high voltage HVDC, by means of the electric charge that is discharged from the capacitative element when the voltage value of the combined signal exceeds the set gate voltage value.
