Thermal performance of power converters is a key issue for the power integration. Temperatures inside active and passive devices can be determined using thermal models. Modelling the temperature distribution of high frequency magnetic components is quite complex due to diversity of their geometries and used materials. This paper presents a thermal modelling method based on lumped elements thermal network model, applied to planar magnetic components made of EE and E/PLT cores. The 3D model is automatically generated from the component's geometry. The computation enables to obtain 3D temperature distribution inside windings and core of planar transformers or inductors, in steady state or in transient case. The paper details the proposed modelling method as well as the automated tool including the problem definition and the solving process. The obtained temperature distributions are compared with Finite Element simulation results and measurements on different planar transformers.

“…Papers [23] propose a method to model the inductance of a busbar by decomposing the busbar into numerous elementary LR segments based on the physical dimensions and structures of the busbar. Paper [24] analyzed the influencing factors of laminated busbars. Techniques concerning inductance minimization are based on reducing the commutation loop size by rearranging the layers disposition [19], [25], [26].…”

High frequency converters based on silicon carbide (SiC) semiconductors are becoming popular, but due to the integration parameters, they are very likely to generate high voltage overshoot and large oscillation, which increase the voltage stress and cause EMC problems. To suppress the voltage overshoot and oscillation, the mechanism is firstly analyzed. Stray inductance is a culprit in causing these problems. To minimize the inductance of power circuit, this paper proposes optimization method including better design of bus-bar structure and parallel connection of snubber capacitors by means of model analysis and formula derivation. To evaluate the method, an inverter model and a prototype were built, several optimization schemes were compared by co-simulation and experimental tests. Experimental results show that the stray inductance of the new bus-bar is 6.4% of the traditional bus-bar. The loop-inductance can be reduced by 46.4% by connecting the capacitors in parallel, and the switching losses can be reduced by 30.8%. This analysis provides guidelines for a full SiC inverter design. INDEX TERMS SiC-MOSFET, low stray inductance, design method, double-pulse test.

“…Ghaedi [9 ] builds 2D model to analyze the concrete dam under seismic action. And Puigdellivol [10] also builds a 2D model to study a topology optimization method for laminated busbars in power converters and he points out that Comparison with 3D FEM proves the 2-D approach to be faster while remaining accurate and a perfect method. However, it is obvious that considering the complexity of large engineering projects like dam, there are too many factors what should be taken into account that 2D theoretical model cannot meet the accuracy requirement.…”

Abstract:The seismic safety of the dam involves the safety of people's life and property, and even affects the overall safety of the national economy. One of the key of technical issues in this subject is the more complete fluid-structure interaction(fsi) theory and the more accurate calculation method. In order to solve the problem of dynamic fluid-structure interaction in gravity dam, a 2.5d semi-dynamic theoretical model and a numerical solution method are established by using fluid slice method. The numerical experiment of seismic displacement response is compared with three-dimensional model. The results show that the displacement response of the 2.5d semi-dynamic model of gravity dam can well reflect the fluid-structure interaction behavior and effect of seismic gravity of concrete gravity dam.
