Abstract: A power supply includes power modules. Each of the power modules includes an input stage configured to convert an input voltage into an intermediate voltage, and an output stage configured to output a DC supply voltage according to the intermediate voltage. Input terminals of the input stages in the plurality of power modules are electrically connected in series, and the input stages are configured to be controlled with at least one first common control signal having a common duty cycle. Output terminals of the output stages in the plurality of power modules are electrically connected in parallel, and the output stages are configured to be controlled with at least one second common control signal having a common duty cycle. A method of supplying power is also disclosed herein.

Abstract: A three-phase AC-DC converter is provided that can offer a low total harmonic distortion (THD) of input current and good power factor with the capability of soft-switching of the active switches. In one aspect, a phase shift is introduced to the gate signal of one of the primary side active switches of the three-phase AC-DC converter and the gate signal of a corresponding one of the secondary side active switches of the three-phase AC-DC converter.

Abstract: A reliable, potting free, and partial discharge free PCB-based inductor is provided. In one aspect, the PCB-based inductor includes an insulating planar board having a central through hole and conductive layers embedded in the insulating planar board. Each of the conductive layers is patterned to have a spiral shape around the central through hole and arranged in an annulus region having an annular radius. The conductive layers are arranged in a staggered pattern, such that the annular radius of the conductive layers increases from the centermost one of the conductive layers to the outermost ones of the conductive layers.
