    摘要: A motor control apparatus includes: a converter configured to convert AC voltage input from an AC power supply side into DC voltage, and then output the DC voltage to a DC side; an inverter configured to convert DC voltage input from the DC side into AC voltage for driving a motor, and then output the AC voltage; and a boosting unit configured to step up DC voltage input to the inverter from the DC side, according to a deviation between a speed command to the motor and speed information acquired from the motor.

    摘要: A hybrid electric vehicle (HEV) includes an inverter control system connected to a transmission such that the connection secures the inverter control system to the transmission during operation while allowing limited pivoting or rotating of the inverter control system relative to the transmission during a frontal collision to modify the translational motion and reduce or avoid loading of rigid objects or components between the inverter control system and the vehicle cabin or occupant compartment. Positioning of an electric cable conduit or connector near or adjacent to the pivot or rotational axis reduces translational force on the conductors to reduce or avoid damage during a frontal collision.

    摘要: An energy generation system includes a turbine, an electric generator, a step-up transformer, and a converter. The turbine is operable to extract energy from a fluid flow and convert the extracted energy into mechanical energy. The electric generator is operable to convert the mechanical energy from the turbine into AC electrical energy. The step-up transformer is operable to transfer the AC electrical energy at a lower voltage from the electric generator to a higher voltage. The converter is operable to convert the AC electrical energy at the higher voltage to DC electrical energy. The converter includes a converter leg for a phase of the AC electrical energy. The converter leg has an upper arm with a first plurality of sub-modules and a lower arm with a second plurality of sub-modules. Each sub-module is operable to function as a controlled voltage source.

    摘要: A method of winding an armature for a rotary converter for converting direct current to alternating current. The rotary converter includes a rotor and a stator. The rotor includes a shaft, a commutator concentric with the shaft, and an armature core concentric with the shaft and adjacent the commutator, the core having slots in its outer circumference parallel to the axis of the shaft. At least one slip ring is mounted on the shaft adjacent the armature core. A first or direct current winding is electrically connected to the commutator and wound in a wave pattern through the armature core slots. A second or alternating current winding is electrically connected to at least one slip ring and wound in a series of alternating clockwise and counterclockwise loops throuth the armature core slots. The rotary converter is particularly suitable for operation from a standard twelve volt battery to supply alternating current at a desired rating to electric tools and the like.

    摘要: Like a transformer that can increase or decrease AC voltage or current by increasing or decreasing the turns-ratio of the transformer an amplification factor is developed. And like a transistor that can amplify/attenuate an electrical signal and by manipulating the hfe of the transistor, it could increase or decrease the amplification factor of the transistor. Likewise, the MAM unit, depending on the number of phases used, can amplify the power for a given output motor by increasing the number of phases of the output AC motor, which substantially reduces the amount of current an AC motor will draw for a specific amount of torque. By increasing the number of phases on an AC synchronous, asynchronous, axial, induction, or reluctance type motor, using alternating current, you can increase the efficiency, which implies an amplification factor of the motor thereby reducing the applied current required for a given amount of torque/speed.
