  • Insulated busbar, insulated busbar fabrication method, and electronic apparatus
    Patent number: 10186475
    Abstract: An insulated busbar includes a plate conductor and insulating films which cover the plate conductor. The insulated busbar further includes conductive films which are formed on inside surfaces of the insulating films so as to be in contact with the plate conductor and which cover a vacant space between an end portion of the plate conductor and the insulating films.
    Type: Grant
    Filed: January 10, 2017
    Date of Patent: January 22, 2019
    Assignee: FUJI ELECTRIC CO., LTD.
    Inventor: Yuji Hayase
  • Insulating busbar and manufacturing method
    Patent number: 10109973
    Abstract: To realize an insulating busbar that has both low inductance and high withstand voltage, provided is an insulating busbar that connects to a module on which is mounted a semiconductor chip, including a plurality of circuit conductors; a plurality of connection terminals that respectively electrically connect the circuit conductors to the module; and an insulating resin portion that is formed integrally between each of the circuit conductors and at least a portion of a region around each connection terminal and does not have any gaps between the circuit semiconductors.
