Abstract: A magnetization state control method for a variable magnetization machine, the method includes generating a flux linkage vector while changing a magnetization state of the variable magnetization machine such that a trajectory of the flux linkage vector has a curved clockwise trajectory on a dq-axis plane and a magnitude of the flux linkage vector temporally changes, with the dq-axis plane being a synchronous reference frame with a d-axis pointing in a direction of a permanent magnet flux and a q-axis being 90 degrees ahead of the d-axis in a rotational direction of a rotor.

Abstract: An electromechanical integrated motor has a motor housing for housing a stator and a rotor, and a power-converter housing for housing a power conversion module integrally joined to the motor housing. The power-converter housing has a radiator wall including the power conversion module attached to a surface on the motor-housing side of the radiator wall, and an outer-peripheral wall having a cylindrical shape, extending further toward the motor-housing side rather than the radiator wall, and being disposed on an outer-peripheral side of the power conversion module. The radiator wall and the outer-peripheral wall are separate members. The radiator wall is supported by the motor housing being capable of rotational movement. A plurality of power conversion modules are attached to the surface on the motor-housing side of the radiator wall, being arranged along a virtual circle having a rotation center of the rotational movement as a center thereof.

Abstract: A soft switching system DC-DC converter includes a switching element, a transformer or a reactor, and a controller configured to control a switching operation of the switching element; and carries out the switching operation of the switching element in a state that a voltage or a current to be applied to the switching element is zero. In a case where a required output value of the DC-DC converter is lower than the minimum output over which soft switching is established, the controller controls the operation of the switching element so that an operation period in which an output of the DC-DC converter becomes the minimum output or higher and a stop period in which the output becomes zero are alternately repeated.

Abstract: A permanent magnet synchronous motor includes a stator, a rotor rotatable relative to the stator, and a magnetic structure with a low coercive force magnet and a high coercive force magnet that are arranged magnetically in series with respect to each other to define a pole-pair of the permanent magnet synchronous motor. A magnetization level of the low coercive force magnet is changeable by a stator current pulse such that a stator magnetomotive force at a rated current is equal to or larger than a product of a magnetic field strength for fully magnetizing the low coercive force magnet and a thickness of the low coercive force magnet.

Abstract: A vehicle has a motor that drives the vehicle, a battery that allows supplying an electric power to the motor, and a power conversion device disposed between the motor and the battery. An execution command of ripple charging and discharging that alternately charges and discharges multiple times with the battery is output to the power conversion device when a temperature of the battery is lower than a predetermined threshold temperature, and the flow rate of the heating medium is controlled such that the flow rate of the heating medium is reduced compared with a case where the temperature of the battery is lower than the temperature of the heating medium when the temperature of the battery is higher than the temperature of the heating medium that exchanges heat with the battery while the ripple charging and discharging is executed.
