  • Patent number: 9425702
    Abstract: A system and method for controlling switching in an AC-AC converter is disclosed. A controller for the AC-AC converter determines a direction of current flow on supply lines that provide AC power to the AC-AC converter and determines a switching pattern for each of a plurality of line-side switches and each of a plurality of floating-neutral side switches in the AC-AC converter based on the determined direction of current flow on each of the supply lines. The controller causes the line-side switches and the floating-neutral side switches to operate in an ON or OFF condition according to the determined switching pattern, such that a controlled current flow is output from the AC-AC converter. The controller also implements a safe-switching routine when transitioning from a first switching pattern to a second switching pattern that prevents a non-zero current from being interrupted during the transitioning between the first and second switching patterns.

  • Patent number: 6993983
    Abstract: A magnetostrictive force sensor universally usable in any environment with similar signals unaffected by the surrounding material. To this end, a sensor comprising a shaft of magnetostrictive material with an inductance coil wound around the shaft is provided with a magnetic shell enclosing the coil only or both the coil and the shaft. Upon application of the magnetic field, the resultant flow of magnetic flux is confined to a path through the shaft and the magnetic shell. By confining the magnetic flux path, the dependency of the sensor signal on the surrounding material and environment is essentially eliminated.

  • Patent number: 6650110
    Abstract: A target wheel sensor assembly includes a sensor that is placed near a target wheel. The sensor includes a magnet to create a flux and a sensing element to sense changes in the flux as the target wheel rotates. The target wheel is alternatingly formed with multiple teeth and multiple slots. Each tooth includes a flat portion that is parallel to the bottom of the sensor and a chamfered portion contiguous to the flat portion. The chamfered portion forms an angle, &agr;, with the bottom of the sensor. As the target wheel rotates, the shape of the teeth in conjunction with the slots cause the sensor to output an asymmetric signal. The shape of the signal is used to determine the direction of motion of the target wheel.

  • Patent number: 6614223
    Abstract: An analog angle encoder having a simply constructed magnet assembly, wherein rotation of a magnetic field relative to a magnetosensitive device provides a varying output of the magnetosensitive device that varies sinusoidally with the angle of relative rotation. The simply constructed magnet assembly is of a closed-path geometry composed of a single piece of magnetic material wherein only a first portion thereof is magnetized for providing the aforesaid magnetic field for the sensor. The remaining portion of the magnet material (the second portion) remains unmagnetized and does not substantially influence the magnetic field produced by the first portion any more than, for example, air would cause.
