β-Ga2O3 is set to revolutionize high-voltage power conversion, with ultra-low losses and a high critical electric field that make it ideal for next-generation power devices, enabling three-phase HVDC AC/DC and DC/AC conversion in the 1–6 kV, 0.5–0.8 kA range for AI data centre power delivery, renewable energy systems, high-voltage circuit breakers, and ESD protection.

With the 2025 release, Silvaco is yet again leading innovation in TCAD, driven by its over 40 years of experience. This release introduces major enhancements across simulation engines, solver performance, physical models, and multi-physics workflows for large-scale 3D applications.

In this paper we will discuss accelerating vertical GaN power technology development with physics-based Digital Twins for 800V DC AI factory power infrastructure.
