CSA Catapult’s Double Pulse Testing service provides application-relevant dynamic characterisation of power electronic devices and modules, using measured switching behaviour rather than static datasheet values.
For system integrators and OEMs, this enables more accurate switching-loss models, improved thermal design and better-informed device comparison, selection and optimisation. By reducing uncertainty under real operating conditions, the service helps engineering teams accelerate design decisions and develop power electronic architectures optimised for efficiency, power density and long-term reliability.
The service automates extraction of key switching parameters directly from measured waveforms, including switching energy, switching speed, voltage and current transients, and reverse-recovery behaviour. This enables fast, repeatable evaluation across hundreds or thousands of operating points, supporting statistically robust data for modelling, validation and design optimisation.
CSA Catapult’s DPT capability supports validation across high-current, high-voltage and temperature-controlled conditions, helping customers reduce losses, improve cooling strategies and increase power density in demanding applications such as electric vehicles, grid infrastructure and AI data centres.
