Madrid/San Francisco/Shenzhen…Frenetic Electronics, the company that offers a pioneering web-based custom magnetics design platform, is responding to industry needs by adding new features that help the solve magnetic challenges faced by its customers. A clear example of this industry-driven approach is Frenetic’s new planar magnetics design and simulation tool. Addressing another challenge, in the automotive sector where thermal constraints and power density are becoming increasingly demanding, Frenetic has introduced capabilities such as potting simulation and liquid cooling plate modeling.
As power electronics systems move toward higher switching frequencies and more compact, integrated designs, planar magnetics are becoming increasingly common, yet also significantly more complex to design due to parasitics, thermal constraints, and integration requirements.
Explains Dr Chema Molina, founder and CEO of Frenetic: “The challenge was not only to enable planar magnetics design and simulation, but to do so while maintaining the level of accuracy engineers expect. Frenetic Planar — our design and simulation tool — addresses this by combining the accuracy typically associated with Finite Element Method (FEM) approaches with the speed of its proprietary analytical models. This allows engineers to quickly explore and validate designs with an average of ~94% accuracy in just a few minutes, enabling significantly faster iterations compared to traditional workflows. We introduced this function to our customers at the end of last year and already around 80% are using it.”
Frenetic Simulator is used across multiple industries, including automotive, aerospace and data centres, each with very different constraints. Rather than building generic features, Frenetic is evolving its platform by working closely with these industries and understanding how magnetic design challenges differ across applications. The new potting simulation capability allows automotive engineers to account for the thermal and electromagnetic impact of resin materials surrounding the transformer, which can significantly affect component behaviour. And cooling plate / liquid cooling support enables the modeling of metallic cooling structures integrated into the transformer and connected to liquid cooling systems, a growing requirement in high-power automotive applications.
Continues Dr Molina: “These developments respond to real challenges faced by engineers designing high-performance magnetic components for next-generation power electronics systems. But our evolving capabilities are not developed in isolation, they originate from a growing demand among Frenetic’s customers. Looking ahead, Frenetic will continue to evolve its platform around the foundations already described: closer collaboration with industry, faster and more accurate design capabilities, and the integration of AI to support early-stage engineering decisions. As further proof of the adoption of our tools, many Chinese companies are already integrating them into their engineering workflows. To support this, we are adding local agents: most recently we signed a deal with Szdore Electronics who will represent us in the China and Asian markets.”
