  • Patent number: 5183387
    Abstract: Fault-tolerant apparatus for controlling first and second input members of a mechanical actuator includes first and second electrical machines and at least two controllers. The first and second electrical machines, which apply braking forces to the first and second input members, respectively, are provided with stators having pluralities of isolated phase windings. Each controller is coupled to a phase winding of the first electrical machine, and also to a phase winding of the second electrical machine. Any one controller can excite the first electrical machine to apply the braking force to the first input member or the second electrical machine to apply the braking force to the second input member.
    Type: Grant

  • Patent number: 5142439
    Abstract: A high-voltage, low-volume capacitor module, having a minimal amount of inherent stray inductance, and being configured so as to allow its integration into an electrical system in a manner which minimizes any stray inductance introduced by interconnection wiring. This is accomplished by integrating the capacitor into the bus bars of the voltage convertor, thereby eliminating the need for separate interconnecting wiring and reducing the overall amount of stray inductance evident within the system in which the capacitor is employed.

  • Patent number: 3986099
    Abstract: A thyristor commutation circuit simultaneously commutates all of the conducting thyristors for a plurality of loads with a single commutating capacitor. Load control circuits for direct current powered loads and both single-phase and multi-phase alternating current powered loads, all with different current requirements, may be commutated at the same time.
