Patent Number Title Of Patent Date Issued
8193749 Control device and control system for electric rotating machine June 5, 2012
A control device has a unit for determining a controlled phase of a controlled voltage outputted from an inverter to a generator according to a difference between a target torque and an estimated torque of the generator, a unit for calculating an instructed vector norm of the control
8193743 Control device for electric rotating machine and method of controlling the machine June 5, 2012
A control device has a unit for preparing a pattern having first and second periods by comparing a triangular wave and a sine wave having an amplitude ratio set at each value of a modulation factor, and selecting one pattern corresponding to an instructed modulation factor, and a unit
7151354 Magnetic noise reduction method for AC rotary electric machine, and motor control apparatus and December 19, 2006
The invention provides techniques for reducing or altering the magnetic noise of an AC rotary electric machine. A magnetic noise reducing harmonic current of order n, whose frequency is n times the frequency of the fundamental frequency component of a polyphase AC current fed to an a
5789881 Power source control apparatus for hybrid vehicles August 4, 1998
A power source control apparatus for parallel and series hybrid vehicles is provided. The power source control apparatus determines a required torque of a power source consisting of a generator-motor and an internal combustion engine based on a parameter indicating an operational mode of
5614803 Inverter control apparatus March 25, 1997
In order to reduce distortion of a real-current wave form and to suppress substantial transient fluctuation of the current and torque during changeover from a regeneration running condition to the power running condition of a three-phase induction motor, changeover from the three-pha
