AI and ML employed to increase accuracy and usability of cloud-based magnetics service

Frenetic Electronics has announced Frenetic AI, an AI-powered assistant designed to help engineers design power converters. The company has also announced significant upgrades to Frenetic Magnetic Simulator, its cloud-based platform that allows engineers to simulate and design high-frequency inductors and transformers with up to 95% accuracy.

The assistant designs the converter topology based on user constraints and automatically generates electrical schematics and simulation files (LTspice, PLECS). It also suggests appropriate off-the-shelf or custom magnetics.

Explains Dr Chema Molina, founder and CEO of Frenetic: "Frenetic AI turns a complex, multi-hour design process into a seamless, intuitive workflow. Engineers can move from specs to simulation in minutes. Basic users receive full magnetic specs automatically, advanced users can deep-dive into detailed customization and simulation options."

Currently available as a free Basic version, which has been beta-site tested by thousands of electrical engineers worldwide, the solution will soon be supplemented by a PRO version, offering premium features such as planar transformer design, off-the-shelf component suggestions, and additional design insights.

The assistant can integrate with Frenetic Magnetic Simulator for advanced magnetic component design, but can also be employed as a standalone module.

Frenetic Magnetic Simulator has also been upgraded. The original platform delivers advanced modelling of copper and core losses, the superposition of AC signals with high-frequency components and material and core selection based on the application's requirements. Latest innovations include a machine-learning-based model for calculating foil winding losses. The new version has been trained on 5,000 FEM simulations across a wide range of designs, delivering a 12% median relative error with millisecond response times.

Adds Molina: "Frenetic Simulator is used 8 hours a day per professionals of magnetic design. The launching of the multiple operating conditions simulation has been another big step to boost the capabilities of optimizing the magnetics never seen before.

"Frenetic is committed to making magnetic design part of a broader, more connected design process. We're currently working with leading simulation software providers to allow engineers to seamlessly export magnetic designs into full FEM environments for advanced validation. The user benefits from reduced manual modelling effort, a faster transition from conceptual design to FEM-level verification, and better alignment between simulation layers," he continued.
