  • Patent number: 10326353
    Abstract: An inductor assembly is disclosed that includes a magnetic core with a center leg and a number n of phase legs, wherein n is an integer and n>1. Each phase leg is magnetically connected to the center leg by an upper bridge and a lower bridge to form a magnetic main loop, a midpoint of the phase leg being magnetically connected to a center point of the center leg by a shunt element including a gap. Each phase leg further includes an upper inductor coil disposed on an upper phase leg section located between the midpoint and the upper bridge and a lower inductor coil disposed on a lower phase leg section located between the midpoint and the lower bridge. Alternatively, the upper and lower inductor coils are disposed on respective upper and lower bridges.

  • Publication number: 20160336846
    Abstract: The disclosure relates to an inductance device for mounting on a printed circuit board including a substantially flat tray and a choke, the choke being mounted on an upper side of the tray and including a core and at least two wound around the core. The wires of the at least two coils comprise end segments that extend through the tray and terminate on a lower side of the tray opposite to the upper side of the tray. The tray includes notches for guiding the end segments through the tray and latches for fixing the end segments of the wires within the notches. The disclosures further relates to an inverter including an inductance device.
