Introduction of Supplied Conductors AC

Introduction

For electrical engineering and power electronics devices, this Supplied Conductors AC “SCAC” solution electrical analysis of 3D complex interconnections thanks to its intrinsic ability to include the impact of non-ideal behaviors (parasitic couplings) of these structures. This solution makes it possible to calculate the electrical current distribution within the structure and its connected active and passive components, as well as the distribution of the Joule losses, which can be evaluated and then displayed as color shades.

The Supplied Conductors AC solution provides the user the ability to compute, for a given set of 3D conductor, dielectric and linear soft magnetic volumes, the frequency-dependent electrical current repartition, and the Joule losses via the definition of a circuit connected to these volumes. The physical pins where electric and electronic components are connected are defined using N-pins Conductor components. The other components available for this solution are resistors, inductors, capacitors, and alternative current / voltage sources.

Note: Due to external circuit connected to conductors, the extraction of equivalent models for system-level tools cannot be performed within this solution; the user is then invited to move to the PE solution.

Moreover, the capability to plot voltage/current in a component as a function of the frequency is available to enable the user to analyze the impact of the so-called resistive, inductive, and capacitive effects to the whole parasitic behavior of the simulated interconnects.

The Joule losses in conductors can also be plotted as function of the frequency: these values can be used to calculate the heat dissipation using Electronics Thermal solution in SimLab (via ElectroFlo solver). This can be done by defining Heat Source LBC for each body using its according Joule losses value.

SCAC Workflow

The typical workflow the user must follow is based on these steps:

Geometry definition by Import CAD/ECAD
Model Discretization
Material and Circuit Designer definitions
Solution Settings (Solver Settings and Result Request and Format and Execute Options)
Solve
Results

All functions are available in the different ribbon bars Geometry, Mesh, Analysis, ...

The content of each ribbon is adapted depending on the active solution.

Main Limitations of the SCAC Solution

Not available for Linux platforms (only for Windows).
Conductive, dielectric and linear soft magnetic materials are accepted. The non-linear soft magnetic and the permanent magnets are not supported.
Mesh limitations:
- Pyramid mesh type is not supported for this version.
- 2^nd order mesh is currently not allowed.
