20060108987 - System and method for determining whether a charging wire is broken: In a system, a generator is configured to charge a battery through a charging wire connecting therebetween. A first unit measures a voltage of the battery, and a second unit detects an operating rate of the generator. A third unit determines that the charging wire is broken when the measured...

20060097703 - Output control device of generation device: An output control device of a generation device including: a rectifier circuit that rectifies an output of an AC generator and applies the output across a battery; an inverter circuit provided between the battery and the generator; inverter control means for controlling the inverter circuit to convert a voltage across...

20060097702 - Position-sensorless control of interior permanent magnet machines: A method of controlling an IPM machine having a salient rotor. Stator terminal signals are measured and rotated to obtain synchronous reference frame current signals. A rotor position is estimated based on an impedance generated using the rotor and included in the current signals. The estimated rotor position is used...

20060091864 - Vehicle power-generation control unit: The vehicle power-generation control unit includes a voltage detecting circuit detecting a generation voltage of a vehicle generator driven by a vehicle engine, a switching device allowing an exciting current to flow into an exciting winding of the vehicle generator when the switching device is in an on state, an...
