EPC’s CEO Analyzes GaN’s Move Into Robotics and Data Centers

Why It Matters

GaN adoption can dramatically improve energy efficiency and reduce size in data centers and robots, accelerating AI workloads and next‑generation automation while cutting operating costs. This positions EPC and other GaN suppliers as critical enablers of the upcoming high‑voltage, high‑density power infrastructure.

Key Takeaways

• GaN enables high‑frequency, low‑loss power conversion.
• EPC targets AI servers, humanoid robots, LiDAR, satellites.
• 800‑VDC data center architecture favors GaN transistors.
• Faster switching reduces torque ripple in robot motors.
• New GaN ICs aim for point‑of‑load delivery.

Pulse Analysis

The rise of gallium nitride (GaN) power devices marks a decisive move away from silicon’s thermal and speed limits. GaN’s superior electron mobility, low on‑resistance, and ability to switch in nanoseconds enable power converters that are both smaller and far more efficient. These attributes have already transformed consumer fast‑chargers, but industry leaders now see GaN as the backbone for high‑density, high‑power applications where every watt and millimeter count.

In data centers, the relentless growth of AI workloads is pushing GPU power consumption past the 3‑kilowatt barrier, straining traditional silicon‑based power paths. The emerging 800‑VDC architecture reduces conversion stages, but it demands components with ultra‑low inductance and rapid transient response. GaN transistors, especially EPC’s 150‑V and 40‑V Gen 7 devices, meet these criteria, allowing power‑factor correction and AC/DC conversion to be moved to side‑car racks while keeping the final stage directly under the GPU. This vertical power delivery reduces board resistance, improves cooling efficiency, and supports liquid‑cooled designs essential for next‑generation AI servers.

Robotics stands to benefit equally from GaN’s speed. Humanoid robots require millisecond‑level motor actuation across dozens of joints, and high‑frequency switching mitigates torque ripple and eliminates dead‑time losses inherent to silicon MOSFETs. By operating at 100 kHz instead of 20 kHz, GaN drives shrink capacitor footprints, extend battery life, and deliver smoother motion—critical for tasks ranging from household assistance to surgical precision. With a projected $38 billion market for humanoid robots by 2035, GaN’s ability to combine power density, thermal performance, and compact form factor positions it as a cornerstone technology for the next wave of intelligent automation.
