CSA Catapult Translates Research Into Double Pulse Testing

Why It Matters

Accurate switching characterization is a growing bottleneck in high‑density AI and data‑center power supplies, so CSA Catapult’s DPT service gives manufacturers a competitive edge in efficiency and time‑to‑market.

Key Takeaways

• DPT tests up to 1.5 kV, 1 kA, 25‑150 °C range.
• Automates extraction of loss, speed, reverse‑recovery parameters.
• Supports SiC, GaN devices and multi‑device power modules.
• Enables OEMs to select components using real‑world performance data.
• Accelerates design cycles, reducing technical risk for AI data‑centers.

Pulse Analysis

Power‑electronics designers for AI accelerators and hyperscale data centres are confronting unprecedented switching speeds, voltage levels, and thermal stresses. Traditional datasheet figures often reflect idealised lab conditions, leaving a gap between simulated performance and real‑world behaviour. As power densities climb, even marginal inefficiencies translate into significant energy costs and cooling challenges, prompting a market shift toward more accurate, statistically robust characterisation methods.

CSA Catapult’s Double Pulse Testing service bridges that gap by automating high‑voltage, high‑current measurements across a broad matrix of voltage, current, temperature, and gate‑resistance settings. The system captures dynamic parameters—switching loss, transition time, reverse‑recovery charge—and translates them into ready‑to‑use models. For SiC and emerging GaN device manufacturers, this means rapid validation of new material stacks and architectures without costly prototype loops. System integrators and OEMs gain a data‑driven basis for component selection, enabling tighter design margins and faster convergence on optimal power‑module topologies.

The broader industry impact is twofold. First, the ability to generate application‑specific switching data at scale reduces technical risk, shortening time‑to‑market for next‑generation AI hardware and data‑center power infrastructure. Second, the service’s compliance with IEC 60747‑8‑4 standards and its roadmap toward higher power levels position it as a foundational tool for the evolving power‑electronics ecosystem. As efficiency gains become a decisive factor in operating‑expense calculations, CSA Catapult’s DPT offering is poised to become a strategic asset for firms seeking competitive advantage in a rapidly maturing market.
