Planar magnetics design for power electronics naturally involves many tradeoffs, especially in the selection of the core size, winding structure and printed circuit board stackup. "Magnetics-in-the-circuit" SPICE simulations can facilitate quick magnetics design evaluation and iteration. This paper introduces and evaluates a "planar-magnetics-in-the-circuit" simulation approach with an M2Spice software tool, which has been developed based on an earlier presented Modular Layer Model (MLM) analysis approach [1]. M2Spice converts the magnetics geometry into a SPICE netlist, which can be simulated with other circuit elements in a power converter under a unified setup. This paper presents an analysis of the applicability and limitations of this approach across wide frequency bands, followed by an evaluation of the accuracy of the SPICE simulation results (by comparing the simulation results to finite-element-modeling (FEM) results and experimental measurements). Multiple planar magnetics prototypes are designed, modeled, simulated, built, and measured, with results reported and discussed.

This thesis presents the design and implementation of a step-down soft-switched dc-dc converter based on an active bridge topology which overcomes some of the limitations of the conventional dual-active bridge (DAB). The topology comprises a double-stacked bridge inverter, coupled to a reconfigurable rectifier through a special three-winding leakage transformer. The converter can run in a low power mode that greatly increases light-load efficiency by reducing core loss and extending the zero-voltage switching (ZVS) range. The converter is implemented with a single compact magnetic component, providing power combining, isolation, and energy transfer inductance.The theory of the converter and its various operating modes, referred to in this thesis as the Double-Stacked Active Bridge converter, is also explored, and a magnetic model of the special three-winding transformer and leakage inductance is presented. The target application is for 380 V dc distribution systems for data centers, where the converter operates for the majority of the time at the nominal input voltage, but must have high efficiency over a wide load range. A 175 kHz, 300 W, 380 V to 12 V prototype converter achieves 95.9% efficiency at full load, a peak efficiency of 97.0%, an efficiency above 92.7% down to 10% load and an efficiency above 79.8% down to 3.3% load.
