Effect of High Temperature Ageing on Active and Passive Power Devices
Résumé
The power devices needed to build a high-temperature converter (inductors, capacitors and active devices) have been stored at 200°C for up to 1000 hrs. Their characteristics have been monitored. Capacitors and magnetic materials from various manufacturers and technologies are tested, as well as silicon-carbide diodes. It is shown that by carefully choosing the components, it is possible to build a reliable power converter operating at high temperature.
