20100026249GENERATOR APPARATUS WITH ACTIVE LOAD DUMP PROTECTION - A generator apparatus includes a generator, a generator controller, and a rectifier bridge. A detector unit for recognizing a load shutoff is also provided. When a load shutoff is recognized, a switch is controlled to be transmissive so that energy produced by the load shutoff is stored in an energy reservoir. From there it can be fed back into the vehicle electrical system.02-04-2010
20110267013SYSTEMS AND METHODS FOR CONTROLLING AN INERTIA OF A SYNCHRONOUS CONDENSER - Systems and methods for controlling an inertia of a synchronous condenser are described. An example system may include a motor, bidirectional power source, and at least one control device. The motor may be configured to alter a rotation of a condenser shaft to obtain a desired inertia of a synchronous condenser during a power disturbance event. The bidirectional power source may be coupled to the motor. The at least one control device may be configured to identify the power disturbance event, determine an amount of power to supply to or receive from the motor to obtain the desired inertia, and control the supply of power from the power source to the motor or from the motor to the power source based upon the determined amount of power.11-03-2011
20120013310Alternator Assembly With Opportunistic Voltage Regulation System - An electrical machine has been developed that opportunistically regulates the voltage supplied to the coil of the electrical machine. The electrical machine includes a stator winding, a rotatable electromagnet, and a voltage regulator. The voltage regulator is configured to control an output voltage of the electrical machine. The regulator is configured to vary the magnitude of the output voltage based at least in part on acceleration of the vehicle.01-19-2012
