Electromagnetic Compatibility (EMC) has become a key and sensitive topic for OEMs and their suppliers in many industries. It is not only important to ensure electromagnetic problems will not occur when integrating components and devices in a system, but also to fulfil the related EMC regulations.
Altair HyperWorks provides leading electromagnetic (EM) simulation software, widely used in many industries and applications to solve a broad range of electromagnetic problems, from static to low and high frequencies. Using these electromagnetic tools within HyperWorks – FEKO and Flux – design teams are empowered to create innovative solutions that meet the challenges of e-mobility vehicle development.
FEKO and Flux are used for EMC to simulate problems related to Electromagnetic Interferences (EMI) and Electromagnetic Susceptibility or Immunity (EMS). ElectroFlo, the newly acquired electronics cooling package designed for high power-density applications, provides users with a broad set of solutions for electronic applications using Flux and FEKO.
FEKO includes a complete cable-modelling tool to analyze both radiation and irradiation of cables into or from other cables, antennas or devices, which can cause disturbance voltages and currents resulting in malfunctioning the system. FEKO is also used to simulate radiated emissions of Electronic Control Units (ECU) in a system, shielding effectiveness, radiation hazard analysis, electromagnetic pulses (EMP), lightning effects and High Intensity Radiated Fields (HIRF).
Typically, EMC testing is performed towards the end of product or system development cycle. One of the biggest risks is that an unexpected problem is uncovered during the testing phase, forcing a design modification and a delay in the product release until certification has been achieved. This raises the question: why wait until the end of the development cycle? In this Interference Technology article, we discuss the importance of EMC and the value of incorporating electromagnetic simulation into the EMC process.
On the other hand, Flux can evaluate the magnetic field radiated by power cables and busbars. The effect of external fields on the operation of electromagnetic devices such as sensors or actuators can be determined. It also allows designing efficient shielding.
For the analysis of EMC phenomena, Flux offers numerous models and capabilities focused on low and middle frequency computations. Accurate, efficient and robust simulation methodologies are provided in Flux 3D – focusing on the study of the magnetic effects of electric energy installations on health as well as magnetic performances of grounding and shielding systems. Flux PEEC, able to analyze stray impedances (R, L and C) of electrical interconnections, as well as common-mode current distributions within power electronics subsystems.
In this Insider blog article, we consider capacitive effects for EMC analysis with the new Flux PEEC software which is part of the Flux 2018 release.
March 2018 sees the release of the 2018 versions of all the HyperWorks EM tools – FEKO, WinProp, Flux and FluxMotor. Find out more in the webinar series.
