Allegro to show how to optimise WBG performance at PCIM
At PCIM 2026, Nuremberg, Germany (June 9-11), Allegro MicroSystems will demonstrate how power designers can unlock the full switching potential of wide bandgap (WBG) devices without the complexity and overhead of legacy architectures.
While SiC and GaN devices support high-frequency switching, they frequently encounter system-level limitations – from bulky external bias supplies to slow protection loops – that impede optimal performance. Allegro will show how integration of sensing and gate driving removes these constraints to enable faster switching, improved efficiency and higher power density in applications like AI data centres and 800V electric vehicle (EV) architectures.
"The industry has built the equivalent of an unrestricted Autobahn for power electronics using WBG materials, but legacy gate drivers and sensors are holding back performance," said Ram Sathappan, VP of global marketing and applications at Allegro. "At PCIM, we are showing how Allegro’s high-bandwidth current sensors and isolated gate drivers can eliminate today’s speed limits on the power conversion freeway."
At the PCIM booth, Allegro will show live demonstrations of itsPower-Thru gate drivers, eliminating the need for external isolated bias supplies and simplifying multi-level designs.
- Active Gate Drive Voltage Control in action, enabling real-time optimisation of SiC switching behaviour via SPI
- High-Bandwidth Current Sensing up to 10 MHz for fast transient detection and protection
- Ecosystem Demos with partners including Coilcraft and Innoscience that illustrate real-world implementations
Together, these demonstrations show how reducing design complexity enables engineers to operate WBG systems closer to their theoretical performance limits – translating directly into efficiency gains and higher system density.
