20070029977 - Electric generation control apparatus for vehicle alternator: An electric generation control apparatus for a vehicle alternator receives an electric generation control signal transferred from an ECU placed apart from the control apparatus through a data transfer line. The control apparatus has a voltage comparator, a communication state judgment circuit, a serial data communication receiver, a PWM communication... Agent: Oliff & Berridge, PLC

20070029978 - Monolithic alternator regulator with configurable regulation modes: An integrated circuit for controlling an alternator circuit in an alternator regulator charging system. The integrated circuit includes a first circuit for performing core regulation functions; a second circuit having a mask selectable operation circuit that allows the integrated circuit to select an operational mode thereof, the mode being selectable... Agent: Ostrolenk Faber Gerb & Soffen

20070024247 - Power generation apparatus using ac energization synchronous generator and method of controlling the same: In a power generation apparatus equipped with an AC energization synchronous generator, when energization of a secondary winding starts to conduct connecting to the network of the AC energization synchronous generator to a network voltage, energization of the secondary winding starts at a fixed frequency and a slip frequency is... Agent: Antonelli, Terry, Stout & Kraus, LLP

20070024248 - Method of calculating power generating torque of synchronous generator: A method of calculating torque of a Lundell-type synchronous generator is disclosed in which only power generation output current and a rotational speed are input for calculation of the amount of electric power and the amount of losses for thereby enabling calculation of power generating torque, based on a sum... Agent: Oliff & Berridge, PLC
