Achieve EMC compliance for electrified vehicles through electromagnetic simulation at vehicle level

Over the past 60 years, the number of electrical components in the automotive industry has exploded. Electrified propulsion leads to high-frequency electromagnetic emissions. In such a context, electromagnetic compatibility (EMC) is a critical challenge that automakers must address to ensure safe and reliable electric cars.

During the webinar, Koen de Langhe – Director of product management, Simcenter Electronics systems simulation, at Siemens Digital Industries Software –, and Erica Van Berkum – Senior Product Manager, Capital Electrical Distribution, at Siemens Digital Industries Software –, will present how the Siemens Xcelerator portfolio allows engineers to simulate and verify EMC performance of vehicles and how this links into the electrical wire harness design process resulting in a connected digital thread for EMC.

Emerging technologies to take electronic performance to the next level of performance

New designs of power electronics systems are emerging, based on silicon carbide (SiC) and gallium nitride (GaN), aiming at a higher level of performance for dedicated applications. Nevertheless, those new technologies also come with particular EMC challenges, both for conducted and radiated EMC. Conducted emission from the inverter into the cables and electrical systems remains a challenge for EMC engineers that needs to be addressed properly.

Utilizing a comprehensive digital twin to address the radiation of electromagnetic noise

In this webinar, you will learn to:

• Establish an end-to-end EMC compliance workflow, including the electrical wire harness and the full 3D geometry of the system
• Apply critical common mode currents resulting from circuital simulation as current sources in a full 3D model of the vehicle and electrical wire harness
• Understand conducted and radiated emissions by analyzing the EM behavior from the source (high voltage cable) to the victims (data communication cables, sensors, etc.)

Regarding electromagnetic compatibility analysis of electrified vehicles, the Siemens Xcelerator portfolio provides design and verification capabilities of all key electrical powertrain systems, such as inverters, batteries, cables and motors at different levels of abstraction. Capital offers E/E system and software architectures, network communications, and embedded software development capabilities. It allows for efficiently designing, engineering, and validating complex products within a digital twin's framework.

With Simcenter electromagnetics simulation solutions, engineers have all the tools to build vehicle-level EM models, including the relevant electrical wire harnesses directly from Capital. With those integrated sets of capabilities, engineers can adequately understand and mitigate EMC concerns efficiently and effectively.
