The National Academy of Inventors (NAI) has officially named Dr. Anant Agarwal, a Professor of Electrical and Computer Engineering at The Ohio State University (OSU), to its prestigious Class of 2025. This election marks a pivotal recognition of Agarwal’s decades-long work in wide-bandgap (WBG) semiconductors—specifically Silicon Carbide (SiC) and Gallium Nitride (GaN)—which have become the unsung heroes of the modern artificial intelligence revolution. As AI models grow in complexity, the hardware required to train and run them has hit a "power wall," and Agarwal’s innovations provide the critical efficiency needed to scale these systems sustainably.
The significance of this development cannot be overstated as the tech industry grapples with the massive energy demands of next-generation data centers. While much of the public's attention remains on the logic chips designed by companies like NVIDIA (NASDAQ:NVDA), the power electronics that deliver electricity to those chips are often the limiting factor in performance and density. Dr. Agarwal’s election to the NAI highlights a shift in the AI hardware narrative: the most important breakthroughs are no longer just about how we process data, but how we manage the massive amounts of energy required to do so.
Revolutionizing Power with Silicon Carbide and AI-Driven Screening
Dr. Agarwal’s work at the SiC Power Devices Reliability Lab at OSU focuses on the "ruggedness" and reliability of Silicon Carbide MOSFETs, which are capable of operating at much higher voltages, temperatures, and frequencies than traditional silicon. A primary technical challenge in SiC technology has been the instability of the gate oxide layer, which often leads to device failure under the high-stress environments typical of AI server racks. Agarwal’s team has pioneered a threshold voltage adjustment technique using low-field pulses, effectively stabilizing the devices and ensuring they can handle the volatile power cycles of high-performance computing.
Perhaps the most groundbreaking technical advancement from Agarwal’s lab in the 2024-2025 period is the development of an Artificial Neural Network (ANN)-based screening methodology for semiconductor manufacturing. Traditional testing methods for SiC MOSFETs often involve destructive testing or imprecise statistical sampling. Agarwal’s new approach uses machine learning to predict the Short-Circuit Withstand Time (SCWT) of individual packaged chips. This allows manufacturers to identify and discard "weak" chips that might otherwise fail after a few months in a data center, reducing field failure rates from several percentage points to parts-per-million levels.
Furthermore, Agarwal is pushing the boundaries of "smart" power chips through SiC CMOS technology. By integrating both N-channel and P-channel MOSFETs on a single SiC die, his research has enabled power chips that can operate at voltages exceeding 600V while maintaining six times the power density of traditional silicon. This allows for a massive reduction in the physical size of power supplies, a critical requirement for the increasingly cramped environments of AI-optimized server blades.
Strategic Impact on the Semiconductor Giants and AI Infrastructure
The commercial implications of Agarwal’s research are already being felt across the semiconductor industry. Companies like Wolfspeed (NYSE:WOLF), where Agarwal previously served as a technical leader, stand to benefit from the increased reliability and yield of SiC wafers. As the industry moves toward 200mm wafer production, the ANN-based screening techniques developed at OSU provide a competitive edge in maintaining quality control at scale. Major power semiconductor players, including ON Semiconductor (NASDAQ:ON) and STMicroelectronics (NYSE:STM), are also closely watching these developments as they race to supply the power-hungry AI market.
For AI giants like NVIDIA and Google (NASDAQ:GOOGL), the adoption of Agarwal’s high-density power conversion technology is a strategic necessity. Current AI GPUs require hundreds of amps of current at very low voltages (often around 1V). Converting power from the 48V or 400V DC rails of a modern data center down to the 1V required by the chip is traditionally an inefficient process that generates immense heat. By using the 3.3 kV and 1.2 kV SiC MOSFETs commercialized through Agarwal’s spin-out, NoMIS Power, data centers can achieve higher-frequency switching, which significantly reduces the size of transformers and capacitors, allowing for more compute density per rack.
This shift disrupts the existing cooling and power delivery market. Traditional liquid cooling providers and power module manufacturers are having to pivot as SiC-based systems can operate at junction temperatures up to 200°C. This thermal resilience allows for air-cooled power modules in environments that previously required expensive and complex liquid cooling setups, potentially lowering the capital expenditure for new AI startups and mid-sized data center operators.
The Broader AI Landscape: Efficiency as the New Frontier
Dr. Agarwal’s innovations fit into a broader trend where energy efficiency is becoming the primary metric for AI success. For years, the industry followed "Moore’s Law" for logic, but power electronics lagged behind. We are now entering what experts call the "Second Electronics Revolution," moving from the Silicon Age to the Wide-Bandgap Age. This transition is essential for the "decarbonization" of AI; without the efficiency gains provided by SiC and GaN, the carbon footprint of global AI training would likely become ecologically and politically untenable.
The wider significance also touches on national security and domestic manufacturing. Through his leadership in PowerAmerica, Agarwal has been instrumental in ensuring the United States maintains a robust supply chain for wide-bandgap semiconductors. As geopolitical tensions influence the semiconductor trade, the ability to manufacture high-reliability power electronics domestically at OSU and through partners like Wolfspeed provides a strategic safeguard for the U.S. tech economy.
However, the rapid transition to SiC is not without concerns. The manufacturing process for SiC is significantly more energy-intensive and complex than for standard silicon. While Agarwal’s work improves the reliability and usage efficiency, the industry still faces a steep curve in scaling the raw material production. Comparisons are often made to the early days of the microprocessor revolution—we are currently in the "scaling" phase of power semiconductors, where the innovations of today will determine the infrastructure of the next thirty years.
Future Horizons: Smart Chips and 3.3kV AI Rails
Looking ahead to 2026 and beyond, the industry expects a surge in the adoption of 3.3 kV SiC MOSFETs for AI power rails. NoMIS Power’s recent launch of these devices in late 2025 is just the beginning. Near-term developments will likely focus on integrating Agarwal's ANN-based screening directly into the automated test equipment (ATE) used by global chip foundries. This would standardize "reliability-as-a-service" for any company purchasing SiC-based power modules.
On the horizon, we may see the emergence of "autonomous power modules"—chips that use Agarwal’s SiC CMOS technology to monitor their own health and adjust their operating parameters in real-time to prevent failure. Such "self-healing" hardware would be a game-changer for edge AI applications, such as autonomous vehicles and remote satellite systems, where manual maintenance is impossible. Experts predict that the next five years will see SiC move from a "premium" alternative to the baseline standard for all high-performance computing power delivery.
A Legacy of Innovation and the Path Forward
Dr. Anant Agarwal’s election to the National Academy of Inventors is a well-deserved recognition of a career that has bridged the gap between fundamental physics and industrial application. From his early days at Cree to his current leadership at Ohio State, his focus on the "ruggedness" of technology has ensured that the AI revolution is built on a stable and efficient foundation. The key takeaway for the industry is clear: the future of AI is as much about the power cord as it is about the processor.
As we move into 2026, the tech community should watch for the results of the first large-scale deployments of ANN-screened SiC modules in hyperscale data centers. If these devices deliver the promised reduction in failure rates and energy overhead, they will solidify SiC as the bedrock of the AI era. Dr. Agarwal’s work serves as a reminder that true innovation often happens in the layers of technology we rarely see, but without which the digital world would grind to a halt.
