    摘要: A control apparatus of a rotary machine controls drive of the rotary machine with winding groups. The control apparatus includes electric power converters in multiple systems, a failure detection portion, and a controller. The electric power converter has switching elements in an upper arm and a lower arm, and converts direct current power. The failure detection portion detects a failure of an electric power converter or a failure of a winding group. The controller operates the switching elements and controls electricity supply. When the failure detection portion detects the failure, the controller stops output to an electric power converter in a failure system, and the controller reduces a total number of times of switching per unit time of the switching elements in a normally operating system.

    摘要: A control system for a motor includes a pulse-width modulation module, a pulse skip determination module, and a duty cycle adjustment module. The pulse-width modulation module generates three duty cycle values based on three voltage requests, respectively. A plurality of solid-state switches control three phases of the motor in response to the three duty cycle values, respectively. The pulse skip determination module generates a pulse skip signal. The duty cycle adjustment module selectively prevents the plurality of solid-state switches from switching during intervals specified by the pulse skip signal.

    摘要: A current measurement module is adapted to measure an observed current level for the inverter. A data processor or mode controller accesses a stored representation of first current level versus rotor speed output at which a total harmonic distortion level is less than threshold total harmonic distortion level. The data processor or mode controller enables the inverter to use SVPWM (space vector pulse width modulation) if the observed current level is less than the first current level for the measured or determined rotor speed. Further, the data processor or mode controller enables the inverter to use DPWM (discontinuous pulse width modulation) if the observed current level is greater than or equal to the first current level for the measured or determined rotor speed.

    摘要: A motor control device includes a PWM signal generation unit configured to increase/decrease a duty in both directions of phase lag side and phase lead side regarding a first phase of three-phase PWM signal pattern. The PWM signal generation unit is configured to increase/decrease a duty in one of the directions of phase lag side and phase lead side regarding a second phase. The PWM signal generation unit is configured to increase/decrease a duty in a direction opposite to that of the second phase with reference to any phase of the carrier-wave period regarding a third phase. A timing point adjusting unit is configured to detect two-phase currents at timing points fixed in the carrier-wave period and to adjust a detection timing point so that the current is detectable at a variable timing point regarding at least one phase when the two-phase currents become undetectable at the fixed timing points.

    摘要: A method for operating a brushless, rotating electrical machine, including at least three phase windings, each of which has a first phase winding terminal and a second phase winding terminal. The phase windings are connected to each other, in particular the particular second phase winding terminals are connected to a shared star point, and phase-width-modulated voltage signals being applied separately to each individual phase winding, and at least one selected phase winding being at least temporarily connected to a constant electrical potential. To minimize switching operations and to reduce the alternating current component of the current source, the pulses of the pulse-width-modulated signals applied to the remaining phase windings are at least temporarily phase-shifted with respect to each other during the period in which the selected phase winding is connected to a constant electrical potential.
