  • Patent number: 10707778
    Abstract: In a control apparatus, a controller performs comparison between a command voltage and a cyclic carrier signal to thereby perform one of pulse-width modulation upon each of first positive and negative peaks of the command voltage being within or identical to the corresponding one of second positive and negative peaks of the cyclic carrier signal, and single-pulse modulation upon each of the first positive and negative peaks of the command voltage being outside the corresponding one of the second positive and negative peaks of the cyclic carrier signal. The pulse-width modulation generates, for each cycle of the command voltage, plural drive pulses based on a result of the comparison. The single-pulse modulation generates, for each cycle of the command voltage, a single positive pulse and a single negative pulse for each cycle of the command voltage based on a result of the comparison.

  • Patent number: 10458513
    Abstract: A damper device according to one embodiment, for example, includes: a rotating member that is rotatable about a rotational axis, the rotating member including a base portion that is plate-like and support portions that is attached to the base portion and extends in an axial direction of the rotational center; and a plurality of weight members disposed partially overlapping each other in the axial direction, the weight members being provided with tracks in respective overlapped parts of the weight members, the tracks guiding the support portion to be swingable with respect to the rotating member, wherein the support portion is shared in the tracks provided in the weight members.
