GaN Beats MOSFETs at All Voltages
Alex Lidow, CEO, Efficient Power Conversion (EPC)
Server architectures are evolving rapidly to meet the extreme power demands of artificial intelligence. Nvidia’s new 800 VDC requirements for Vera Rubin–class AI servers, combined with power levels reaching up to one megawatt per rack, are driving the need for new device technologies and power conversion architectures. EPC has developed GaN devices that set new benchmarks across the entire 800 VDC power chain - from the 800 V input down to the point of load - surpassing the performance of any MOSFET ever developed and defining the future of AI power systems.
Leveraging Test-to-fail Methodology to Ensure Reliable Field Operation of GaN Devices
Shengke Zhang, Vice President of Product Reliability, Efficient Power Conversion (EPC)
GaN transistors and ICs have gained significant traction as an emerging technology for advanced applications such as LiDAR, AI data centers, humanoid robots, and space systems. The robustness and stability of GaN devices are key factors for the widespread adoption of this technology. EPC has developed a test-to-fail methodology to quantitatively model device lifetimes under various mission-specific operating conditions. The results demonstrate the excellent reliability robustness and stability of EPC’s eGaN technology under field operation.

GaN Inverters Reference Designs for Humanoid Robot Motor Joints
Marco Palma, Director, Motor Drives Systems and Applications, Efficient Power Conversion (EPC)
Humanoid robots are seeing strong market growth across a wide variety of applications. The key market segments for humanoid robots are industrial automation, warehouses, household assistance and healthcare and agriculture. According to Goldman Sachs research, the global shipment of humanoid robots in 2025 was between 15,000 and 20,000 units and a strong Cumulative Annual Growth Rate (CAGR) of over 40% is expected over the next decade. Motor control forms a key design aspect in robotics, and in this presentation, we summarize the basic motor joints architecture and related requirements for the power electronics, along with examples of motor drive reference designs available from Efficient Power Conversion Corporation (EPC).
800 V to 12 V AI Servers using Low-Voltage GaN in an ISOP Converter
Michael de Rooij, GaN Applications Fellow, Efficient Power Conversion (EPC)
Next generation 800 V server rack architectures, driven by AI, have increased the competition between computing hardware and power supplies for rack space thus encouraging the adoption of new high-efficiency, high-power-density conversion topologies. The Input Series Output Parallel (ISOP) has emerged as a leading candidate that can meet the efficiency and power-density demands for these servers. EPC has developed a 8-LLC-module, 6 kW, 800 V to 12.5 V isolated ISOP converter using 150 V and 40 V rated GaN FETs only, that fits in a volume of just 47 x 106 x 8 mm. This presentation will provide details of the design, experimental results and cover the benefits of using 8-modules over alternative approaches.
