Revolutionary advances in semiconductor expertise promise quicker EV charging, extra environment friendly vitality conversion, and a significant leap ahead in high- and low-voltage energy techniques—paving the best way for a better, greener future.
The Fraunhofer Institute for Utilized Strong State Physics IAF is about to showcase developments in energy electronics utilizing gallium nitride (GaN) expertise—breakthroughs that promise to speed up the vitality transition and bolster Europe’s financial resilience.
Central to their presentation is a extremely built-in monolithic bidirectional change (MBDS) able to dealing with 1200 V, providing a compact and environment friendly answer for grid-connected energy converters and electrical automobile techniques. Developed below the GaN4EmoBiL undertaking, this innovation integrates free-wheeling diodes and leverages Fraunhofer’s proprietary GaN-on-insulator expertise, utilizing substrates like silicon carbide and sapphire to enhance insulation and breakdown voltage. This structure reduces conduction losses and saves chip area by enabling bidirectional present circulate via a single cut up depletion area.

“The added worth of modern energy electronics is evident: higher efficiency, improved effectivity, and better energy density,” mentioned Achim Lösch, Enterprise Developer for Excessive Frequency and Energy Electronics at Fraunhofer IAF. “These enhancements translate immediately into faster-charging electrical autos and extra environment friendly renewable vitality techniques.”
With present EVs usually utilizing 400 V techniques and 800 V gaining recognition, Fraunhofer’s 1200 V GaN MBDS paves the best way for next-gen electrical autos and heavy-duty electrical vehicles with quicker charging and diminished vitality loss. Dr. Michael Basler will current the total particulars of this growth on Might 8 on the PCIM convention in his speak, “Extremely-Built-in 1200 V GaN-Primarily based Monolithic Bidirectional Change.”
Fraunhofer IAF can also be breaking new floor within the low-voltage area. Researchers have efficiently applied a single-gate GaN HEMT as a bidirectional change in a 3-level T-type converter for voltages as much as 48 V. This method simplifies management in comparison with dual-gate options whereas sustaining effectivity and compactness. Daniel Grieshaber will current this work on Might 6, in his session titled “Investigation of a Single-Gate GaN HEMT as Bidirectional Change in a Low Voltage Multilevel Topology.”
