Proceeding electrification including automotive power electronics demands increased power density, miniaturization, and elevated operating temperatures. One crucial component to define the cost, size, energy efficiency, and reliability of power electronics is the DC link capacitor. For this purpose, CeraLink capacitors are perfectly suited due to their high capacitance density, high operating temperatures, low inductance, as well as low losses in operation. This includes, especially, the combination with state-of-the-art power switches based on GaN and SiC. CeraLink relies on the ceramic material PLZT (lead lanthanum zirconate titante) and is characterized by a high energy storage capability due to the antiferroelectric phase. This presentation provides an overview of material and device requirements for capacitors based on antiferroelectric materials.
