“…In fact, the wiring inductance should be considered in the test circuit simulation as an inductor matrix to take into account the effects of the mutual inductances in addition to the proper inductances. In this paper, the wiring parasitic model of the switching cell circuit is selected to be established using the commercial software INCA [20]. However, other parasitic extraction tools like Q3D [21] may also be used.…”

Power converter design requires simulation accuracy. In addition to the requirement of accurate models of power semiconductor devices, this paper highlights the role of considering a very good description of the converter circuit layout for an accurate simulation of its electrical behavior. This paper considers a simple experimental circuit including one switching cell where a MOSFET transistor controls the diode under test. The turn-off transients of the diode are captured, over which the circuit wiring has a major influence. This paper investigates the necessity for accurate modeling of the experimental test circuit wiring and the MOSFET transistor. It shows that a simple wiring inductance as the circuit wiring representation is insufficient. An adequate model and identification of the model parameters are then discussed. Results are validated through experimental and simulation results.

Accurate simulation is an essential task in designing of integrated power systems to predict their electrical behavior. Thus, a very good description of their wiring circuits is required, and the availability of accurate models of power semiconductor devices and associated design parameters is crucial. This paper focuses on a novel extraction approach of design parameters for a 1-D finite-element-method model of the thyristor. These design parameters are also essential for physics-based analytical models. This paper presents an extraction procedure of the main design parameters of an ultrafast thyristor: the effective area of the device, the ambipolar lifetime, the doping concentration and width of the low-doped base region, and the doping concentration and width of the gate region. The extraction procedure of the thyristor design parameter is based on a comparative computation between simulation and experimental results, taking into account the physics of the component. Measurements are carried out on a sophisticated test circuit, which must be modeled with a sufficient accuracy. This paper details the parameter extraction procedure. Various electrothermal simulation results about the thyristor under test, using the extracted values of design parameters, show good agreement with experiment and confirm the validity of the presented extraction procedure.

“…The authors presented a numerical approach combining analytic modelling with simulation to compute thermal resistances and equivalent parasitic capacitors. In [6], the authors focused on thermal behaviour and parasitic parameters to optimize the layout of power modules. They suggested defining a grid of possible locations for the electronic components, running simulations for every location and storing results as matrices.…”

Nowadays, the design of Power Modules (PM) is shared between multidisciplinary teams of designers using various modelling tools. Consequently, optimizing the layout of PM is a long process with high risk of errors.In this paper, a sequentially coupled approach is proposed to optimize this process. This integrated method is based on coupling physical models and applying an optimization process. It is illustrated through the example of the layout of a half-bridge Mosfet power module exposed to electric and thermal constraints. So, physical models and software components have been developed, in order to define the multidisciplinary design process and then to perform the layout optimization using the NLPQL algorithm.It is shown that, the proposed approach allows automatic data exchange between physical models and optimal configurations are proposed with reduced design time and risk. Therefore, this integrated approach shows a great improvement in the design of PM and multidisciplinary products.
