   Application of a multi-winding magnetic component characterization method to optimize cross-regulation performances in DCM flyback converters
By Denis MOTTE-MICHELLON [View]
[Download]

Abstract: In this paper, output voltage deviations issues in multi-output DCM cross-regulated flybacks are studied, with a particular focus on the transformer. Using the extended Cantilever model, a general explanation of the influence of the transformer on voltage deviations is developed. Then, an application of an analytical model based on a formulation of the magnetic vector potential allowing to characterize the transformer around 1,000 faster than its finite-element method (FEM) equivalent is presented. This characterization method, fast and accurate, offers the possibility to create a design aid tool for the transformer manufacturer, allowing to define the winding layout with the best cross-regulation performances for a transformer taking place in a given converter.

   Design Space Exploration for a Capacitive 36V, 4A, 4:1 DCDC Converter with GaN Switches Using a Performance-Cost-Matrix Including Uncommon Topologies
By Adrian GEHL [View]
[Download]

Abstract: A systematic approach to compare capacitive DCDC converters regarding performance and cost is presented. All possible topologies for a 4:1 voltage conversion ratio are generated using an algorithm developed in this research. Selected topologies are implemented benefiting from GaN transistors. Experimental results over various operating conditions up to 36 V input, 4 A load and 2 MHz switching frequency confirm theory and simulation. Two uncommon topologies demonstrate superior cost and load performance. The parameter space supports various industrial and automotive applications.

Abstract: This work uses design by optimization of power electronics converter to achieve the best Levelized Costof Energy in a PV application. The methodology uses detailed models of power electronics active andpassive components to determine the cost and performances of the solid-state energy conversion, andconnect them to the system level vision. The deterministic algorithm used for converter sizing allowstaking into account a large number of variables and constraints. Methodology, models and someillustrations of the results are provided in this paper.
