“…Examples show that the optimization process -based on a genetic algorithm -can lead to a smaller / lower cost inductor and capacitor design. Juds et al [4] and Profumo et al [8] describe heat transfer inside thyristors by linear diffusion and distributed resistor and capacitor (RC) networks and present RC equivalent thermal models. Bruckner and Bernet [9] discuss the difficulties and quantify the limitations of this approach with the example of a three-level voltage source converter with insulated gate bipolar transistors.…”

“…Even though the variation of the thermal properties of the device material with temperature can also influence the solution of the thermal problem, this effect is not included into the model definition. Some equivalent electrical analog networks are proposed in order to implement the model in a convenient form, and the predictions from the model are first compared against a coupled thermal and electrical model using a resistance/capacitance network approach [4]. Experimental results are then used to validate the model.…”

“…Comparison with a model based on a resistance / capacitance network approach: A first step toward validation of the model is to compare its results with results obtained when using a coupled thermal and electrical time-domain model based on the electrical analogy for thermal resistance, thermal capacitance and airflow. This model[4] includes the medium voltage power circuit, the control algorithms, the induction machine model, and a transient thermal model and has been validated experimentally. This comparison is made inFig.…”

Adverse effects of starting-torque transients and high in-rush currents in induction motors are typically mitigated by employing electronically controlled soft starting voltages through silicon controlled rectifiers (SCRs). However, the heat dissipation in the soft starter must be carefully managed in the design of motor drives. The objective of this study is both to address the heat dissipation in the soft starter by implementing analytical solutions to the heat diffusion equations inside the soft starter, and to investigate the use of a phase change material (PCM)-based heat sink for thermal management of the device. The analytical modelling approach is, however, general, and can be applied to the solution of a range of thermal problems in power electronics. The transient analytical thermal model, based on the thermal quadrupole approach, allows a determination of the transient performance of a soft starter by evaluating the thyristor junction temperature. Predictions from the model are first compared to results obtained using a coupled thermal and electrical model based on a resistance/capacitance network approach. Experimental results obtained with the soft starter connected to a low-voltage 200 hp induction machine are then used to validate the model. Additionally, the performance improvement resulting from the use of a hybrid heat sink (plate fin heat sink immersed in a PCM) is evaluated and compared to a conventional air-cooled heat sink without a PCM under identical conditions.

“…Uma outra abordagem encontrada para a modelagem de aquecimento é o uso de circuitos térmicos equivalentes. Esta é técnica empregada em [30] e [40] para a modelagem do aquecimento do tiristor do sistema de partida suave de um motor de indução trifásico. Nestes trabalhos os parâmetros do circuito térmico equivalente foram calculados a partir das características dos materiais usados.…”

View full text Add to dashboard Cite

This paper presents a blended analytical electrical–thermal model for steady state thermal analysis of through-silicon-via (TSV) in three-dimensional (3D) integrated circuits. The proposed analytical model is validated by the commercial FEM tool—COMSOL. The comparison between the results of the proposed analytical formulas and COMSOL shows that the proposed formulas have very high accuracy with a maximum error of 0.1%. Based on the analytical model, the temperature performance of TSV is studied. Design guide lines of TSV are also given as: (1) the radius of the TSV increases, the resistance decreases and the temperature can be increased; (2) the thicker the dielectric layer, the higher the temperature; (3) compared with carbon nanotube, the Cu enlarges the temperature by 34 K, and the W case enlarges the temperature by 41 K.
