  • High frequency inverter transformer for power supplies
    Patent number: 4536733
    Abstract: A low leakage inductance inverter transformer utilizing a torodial ferrite core having a primary winding wound thereon, with the secondary winding constructed from stamped conductive clips ranged to encompass portions of the core and primary winding with clip interconnections formed by printed circuit interconnections is described. The conductive clip described includes integral pins for making connection to printed circuit wiring on a printed circuit board. The turns ratio is selected by the pattern of printed circuit interconnection of the conductive clips such that the transformer structure turns ratio is established by the associated printed circuit interconnection pattern.
