Infineon CoolGaN™ technology enables new levels of efficiency and power density in BRC Solar’s Power Optimizer - EEJournal

Infineon Technologies AG has announced that BRC Solar GmbH has selected Infineon’s CoolGaN™ technology as the core switching technology for its Power Optimizer. The CoolGaN™ Transistor 100V family del... Read original →

Infineon’s CoolGaN™ adoption by BRC Solar signals GaN’s strategic shift from consumer chargers to industrial renewable energy systems. Technically, GaN’s high-frequency, low-loss operation shrinks magnetics and enables panel-level MPPT miniaturization, forcing upstream IC and packaging suppliers to adapt to extreme dv/dt conditions. Regulatory tailwinds—like the EU’s ERP Lot 20 and CBAM—will inflate hidden costs for silicon solutions, giving GaN a compliance edge. Competitors like STMicroelectronics and Navitas will likely accelerate integration of automotive and solar GaN platforms to counter Infineon’s vertical dominance in industrial power. Within 18 months, GaN penetration in distributed PV is poised to exceed 15%, catalyzing a new product paradigm fusing 3D integration with cloud-based energy analytics—where efficiency alone no longer wins, but energy-density multiplied by digital service does.
