EMC Professional Talk: High-Fidelity EMC Simulations for WPT-Systems: Real-Time, Data-Driven, and in the Loop
Wireless power transfer (WPT) systems based on low to middle frequency magnetic field induction are rapidly becoming an alternative to a conduction-based power transfer in many technical applications. This includes a wide range of applications from mobile phones, electric toothbrushes, inductively powered cooking appliances to battery electric vehicles.
The magnetic stray fields of these WPTs are subject to restrictions recommended by the International Committee for Non-Ionizing Radiation Protection (ICNIRP), as they may cause potentially harmful effects due to induced electric fields in biological organisms exposed to these fields. Related environmental electromagnetic compatibility analyses involve advanced numerical electromagnetic field simulations, typically featuring high-resolution exposure scenarios and human body models, as well as problem-adapted quasistatic field models. Computationally expensive, high-fidelity exposure simulations with tens of billions of mesh cells on multi-GPU-accelerated supercomputers are now state-of-the-art. Recent research efforts aim to replace these brute-force computer analyses with more computationally efficient simulations based on data-driven surrogate models. These models enable near real-time simulations on low-cost hardware and allow on-site measurements to be integrated into the simulation loop.
