Ceramic capacitors for fast high voltage PSUs

This post was originally published on this site

Kemet is aiming at fast-switching wide bandgap semiconductor (GaN or SiC) power supplies with high-voltage multi-chip ceramic capacitor assemblies. The parts, branded ‘KC-Link with Konnekt’, feature multiple separate ceramic capacitors bonded together using a copper-tin alloy by a process dubbed ‘transient liquid phase scintering’ (TLPS) – see diagram. “High mechanical robustness allows KC-Link capacitors with Konnekt …
