  • Patent number: 7688039
    Abstract: A control device measures a voltage drop across a conductor in a generator to determine and control the total generator output current. A temperature of the conductor is also measured to improve the accuracy. The control device may further improve on the accuracy by compensating for the electrical current through a field coil that may power the generator. The control device may be used in combination with a generator in a vehicle electrical system. Other system parameters may be monitored to improve on the system monitoring, diagnostics, and control. The generator may include a conductor comprising a process-controlled geometric shape.

  • Patent number: 7635922
    Abstract: This invention discloses a power control system comprising a prime mover and a generator driven by the prime mover. A control device is coupled with the generator to ascertain a change in speed of the generator and vary an output power of the generator according to the change. The control device applies a signal to reduce the generator output power and another signal to restore the generator output power. The power control system may include a transmission, a speed converter, and/or an accessory.

  • Patent number: 7432613
    Abstract: A high current, light weight, thermally stable, bidirectional semiconductor switch module in an electrical system uses MOSFET technology in a back-to-back parallel architecture. The device comprises a controller which permits it to operate in high electrical noise environments. The device is further controlled to operate in either or both directions based on external events such as voltage changes associated with the electrical system and with vehicle operating conditions. The device operates at currents typically from a few amperes to 1000 amperes and may be used as a circuit breaker, over voltage switch, isolation switch, transient protection switch, and voltage converter. The device functions to replace the solenoids and relays associated with starter motors in a vehicle electrical system.
