<5nH Low Inductance Film Module for DC-LINK for EV

WIMA low-inductance DC-LINK capacitors are characterised by a flat, space-saving design with very low self-inductance, typical ESL of 3nH. In addition to general applications, they are particularly suitable for applications in combination with silicon-based SiC power semiconductors.

The Benefit

The traditional method of DC-LINK is one of compromise using off-the shelf capacitor modules and bus bars.  Optimum efficiency was rarely achieved as a result. WIMA low-inductance DC-LINK capacitors allow for a clean sheet approach allowing for smaller, neater, system designs.

Customers work directly with a dedicated team of WIMA engineers to fully optimise the design from an electrical and mechanical standpoint, even down to the metallisation of the film!  The integrated bus bar is designed for direct connection to the power modules offering true flexibility for the positioning of power connections. The flat design allows for a straightforward liquid cooling arrangement.

Applications

Applications include inverters and drives, typically for EV motor drives.  Users who could benefit from this technology solution include automotive manufacturers or anyone requiring an optimised DC-LINK with a very low ESL.
