An apparatus is configured according to a transformer based step down topology is provided. The apparatus includes a first transformer that transfers energy from a primary side of the first transformer to a secondary side of the first transformer for driving a load at the secondary side. The apparatus includes a first inductor and a second inductor electrically coupled at the secondary side. The apparatus includes a primary side directional conducting element and a secondary side directional conducting element configured to perform a first phase of transferring the energy through the first inductor and a second phase of transferring the energy through the second inductor. The first inductor induces the second inductor to transfer energy during the first phase and the second inductor induces the first inductor to transfer energy during the second phase.

Transient performance for apparatus with electrically coupled output inductors

An apparatus such as a power supply includes a controller and multiple power converter phases. The controller controls operation of the multiple power converter phases to produce an output voltage that powers a load. The multiple power converter phases are coupled in parallel to convert an input voltage into an output voltage. The controller further controls a flow of current through a series circuit path connecting multiple windings of the multiple power converter phases to operate the power supply in different modes.

Trans-inductance multi-phase power converters and control

According to one configuration, an inductor device comprises core material and at least a first electrically conductive path. The core material is fabricated from magnetically permeable material. The first electrically conductive path extends axially through the core material from a proximal end of the inductor device to a distal end of the inductor device. The core material is operable to confine first magnetic flux generated from first current flowing through the first electrically conductive path. The inductor device further includes a gap in the core material. The gap (gas or solid material) has a different magnetic permeability than the core material. Inclusion of the gap in the core material provides a way to tune an inductance of the inductor device and increase a magnetic saturation level of the inductor device. The core material includes any number of electrically conductive paths and corresponding gaps.
