  • Inverter apparatus
    Patent number: 11923122
    Abstract: Systems, apparatuses, and methods are described for an inverter which receives a direct current (DC) input, and outputs an alternating current (AC) output. A high AC voltage is achieved by serially connecting AC outputs from inversion modules included in the inverter. Multiple inversion stages are serially connected in order to form the AC output. Windings around a common core of the inverter may cause ripple currents to be shared by the inversion modules. Utilizing a common core enables reducing low frequency ripple currents.
    Type: Grant

  • Transformer Apparatus
    Publication number: 20240062952
    Abstract: Systems, apparatuses, and methods are described for a transformer supporting two or more sets of windings electrically connected to different voltage levels. Use of stress control materials or composite materials (comprising a matrix and filler) may direct electrical fields caused by the different voltage levels to have a lowered electrical field amplitude.

  • Transformer Apparatus
    Publication number: 20210027936
    Abstract: Systems, apparatuses, and methods are described for a transformer designed for supporting two or more sets of windings referenced to different voltage levels. Use of semiconductive shields may direct electrical fields caused by the different voltage levels to have a first amplitude in a first region of the transformer and a second amplitude in a second region of the transformer, and may enable efficient and cost-effective use of insulating materials and transformer design.

  • Partially-Conducting Transformer Bobbin
    Publication number: 20190355510
    Abstract: A bobbin, which may comprise a hollow cylindrical shell, wherein the hollow cylindrical shell may define or otherwise comprise an inner cavity. The bobbin may comprise one or more flanges located near an end of the hollow cylindrical shell, wherein the flange(s) extends, at least in part, radially away from the inner cavity, wherein the flange(s) comprises a region of partial conductivity.
