  • Patent number: 12283881
    Abstract: An improved distributed-output multi-cell-element power converter utilizes a multiplicity of magnetic core elements, switching elements, capacitor elements and terminal connections in a step and repeat pattern. Stepped secondary-winding elements reduce converter output resistance and improve converter efficiency and scalability to support the high current requirements of very large scale integrated (“VLSI”) circuits. Some embodiments of the multi-cell converter comprise integrated secondary-side switching devices comprising control circuitry that monitors circuit conditions to determine when the switching device is to be ON and OFF, thereby eliminating the need for secondary-side switch control signals and signal buses, primary-to-secondary interface circuitry and centralized drive circuitry.
