摘要： A method and apparatus for adaptively configuring an array of voltage transformation modules is disclosed. The aggregate voltage transformation ratio of the adaptive array is adjusted to digitally regulate the output voltage for a wide range of input voltages. An integrated adaptive array having a plurality of input cells, a plurality of output cells, or a plurality of both is also disclosed. The input and output cells may be adaptively configured to provide an adjustable transformer turns ratio for the adaptive array or in the case of an integrated VTM, an adjustable voltage transformation ratio for the integrated VTM. A controller is used to configure the cells and provide digital regulation of the output. A converter having input cells configured as a complementary pair, which are switched out of phase, reduces common mode current and noise. Series connected input cells are used for reducing primary switch voltage ratings in a converter and enabling increased operating frequency or efficiency. An off-line auto-ranging power supply topology is disclosed. An auto-ranging converter module (“ACM”) includes 2 or more input cells magnetically coupled to an output cell providing auto-ranging, isolation, and voltage transformation. The ACM converts a rectified line voltage to a low DC bus voltage. The topology allows regulation and power factor correction to be provided at a low voltage increasing energy density and efficiency and reducing cost. A fully integrated PCM may also include a hold-up circuit, a DC input, and a power regulator with or without power factor correction. A PCM with PFC may combine the hold-up and smoothing capacitors for further increases in power density. A universal AC adapter architecture is shown using a unipolar bus to distribute power to one or a plurality of stationary or mobile electronic devices.

摘要： A droop compensation system includes a controlled current source that provides a scaled model of the PRM output current or VTM input current on an interface connection. A controlled resistance modeling the VTM effective series input resistance is connected across the interface terminal. The voltage developed across the controlled resistance by the controlled current establishes a correction signal representative of the VTM droop that is used to adjust the PRM output thereby compensating for the droop. A VTM control interface provides a mechanism for enabling and disabling the VTM. The VTM control circuitry may be powered by the interface connection, allowing the VTM to operate and process power when the VTM input voltage is below its normal minimum operating voltage, increasing the VTM dynamic range and allowing “soft start” into a capacitive load.

The converter has a top surface above the first surface and a bottom surface below the first surface. A border of the bottom surface is inset from a border of the second surface. The connection device includes a pair of conductive legs, each leg comprising a first end and a second end.

摘要： A bobbin is adapted to support a winding on a permeable core and has a wall that provides a confined thermally conductive channel that causes conduction of heat along a predetermined path from the core to a location outside the winding. A value of magnetizing inductance in a transformer is set by adjusting the gap until the value of magnetizing inductance has been set and attaching a segment of the bobbin to a pair of core pieces to maintain the gap. A permeable strip provides a permeable path outside of the hollow interior space and does not couple the winding, and an electrically insulating coupler is interposed between the slug and the winding to electrically insulate the winding.
