Abstract: In a vehicle, a control apparatus controls a power converter supplying a rotary machine which can operate as a drive motor of the vehicle, and controls a cooling apparatus for circulating a coolant fluid through the rotary machine and the power converter. When a temporary condition occurs immediately after commencement of the circulation, whereby the temperatures of the coolant fluid and of switching elements in the power converter are judged to concurrently exceed respective specified temperature thresholds, the control apparatus limits the maximum power that can be supplied from the power converter to a lower value than is normally available. When the temperature of the coolant fluid is judged to no longer exceed the corresponding temperature threshold, the limiting is released.

Abstract: A control device for a rotating electrical machine is provided that is capable of suppressing reduction in controllability of torque attributed to harmonic currents. According to the exemplary embodiment of the present invention, a designated torque value Trq* designated by a hybrid vehicle electronic control unit (HVECU) is corrected by a compensation amount ΔTrq calculated using a harmonic voltage Vh, the designated torque value Trq*, and an electric angular velocity ω as inputs. An operating signal generating section generates an operating signal g¥# using a designated norm value Vn set based on the corrected torque designated value Trq* and a phase δ serving as a manipulated variable for performing feedback control of an estimated torque to the designated torque value Trq*, and outputs the generated operating signal g¥# to a power supply circuit of a motor generator.

Abstract: In a control apparatus, a target harmonic current obtainer obtains, according to a phase current flowing through at least one phase winding of a stator of a rotary machine, a target harmonic current component flowing in the rotary machine. The target harmonic current component correlates with a fundamental current component of a phase current. An inducing unit superimposes, on at least one of the amplitude and the phase of an output voltage vector of a power converter used by a switching unit, a harmonic signal that changes at an angular velocity identical to an angular velocity of the target harmonic current component. This induces a counteracting harmonic current component in the at least one phase winding. The counteracting harmonic current component counteracts the target harmonic current component.

Abstract: In a control apparatus, a target harmonic current obtainer obtains, according to a phase current flowing through at least one phase winding of a stator, a target harmonic current component flowing in a rotary machine. The target harmonic current component is included in a fundamental current component of the phase current. An inducing unit superimposes, on the phase information, a fluctuating signal that changes at an angular velocity identical to an angular velocity of the target harmonic current component, to induce a counteracting harmonic current component in the at least one phase winding. The counteracting harmonic current component counteracts the target harmonic current component.
