    摘要： A converter controls a system voltage, which is a DC link voltage of an inverter, in accordance with a voltage command value. The inverter outputs a rectangular wave voltage having the system voltage as amplitude to an AC motor during application of rectangular wave voltage control. During application of rectangular wave voltage control, a voltage command value for the system voltage is modified such that a current phase on a d-q plane of the AC motor is brought closer to a target current phase line. The target current phase line is set on an advance side relative to an optimal current phase line which is a set of current phases at which output torque is maximized for the same amplitude of a motor current in the AC motor.

    摘要： An electrophotographic photoconductor in which generation of a ghost phenomenon caused by exposure is avoided and potential change before and after continuous printings is insignificant. A functionally separated type electrophotographic photoconductor includes at least a charge generation layer containing a charge generation agent and a charge transport layer containing a charge transport agent, the two layers being sequentially laminated on a conductive substrate. A ratio of the maximum intensity of a halo pattern to a peak intensity of a maximum diffraction peak is less than 0.3 in an X-ray diffraction pattern obtained by a powder method using Cu Kα line of a test coating film produced from a test coating liquid that is prepared by adding the charge transport agent into a coating liquid for the charge generation layer in an equal mass of the charge transport agent to a mass of the charge generation agent.

    摘要： Fluctuations in output of an AC electric motor are restrained without increasing electromagnetic noise of a boost converter. When subjecting the AC electric motor to rectangular wave voltage control, output torque T is controlled by varying a voltage phase φv. In a region where a voltage phase is large (φv=θ2), fluctuations in torque T relative to changes in a DC voltage VH corresponding to the amplitude of a rectangular wave voltage are larger than in a region where the voltage phase is small (φv=θ1). The AC electric motor is controlled such that the rectangular wave voltage control in a region where voltage phase φv is larger than a limit-phase line PLN indicated by a set of limit phases set for each DC voltage VH is avoided.

    摘要： A hybrid vehicle generates vehicle driving force by the sum of a direct torque mechanically transmitted directly from an engine to a drive shaft through a power split device and an output torque of an MG. A PM-ECU selectively applies a running mode in which outputs of the engine and the MG are controlled such that the requested driving force for the entire vehicle is exerted on the drive shaft; and an S/D mode in which the requested driving force is exerted on the drive shaft by the direct torque in the state where the output torque of the MG is set at zero. An MG-ECU stops the operation of a power converter for controlling the output of the MG when the S/D mode is applied.
