DC-LINK Capacitors for SiC-Power Semiconductors

2021-06-08
■WIMA low-inductance (LI) DC-LINK capacitors are characterized by a flat, space-saving design with particularly low self-inductance. In addition to general applications, they are particu-larly suitable for applications in com-bination with silicon-based SiC power semiconductors
■Advantages
●The LI configuration with flat, space-saving design is available for all types and contact configurations ●Existing capacitor designs can easily be substituted with LI capacitors
●The LI design has no restrictions regarding the energy density per volume compared to previous DC-Link configurations
●The WIMA Single Side Cooling (SSC) achieves ideal heat dissipation with one-sided (water) cooling systems
●The LI design is available in 2- and 3-voltage level configurations
■Properties
●Low leakage inductance of≤10 nH in almost any capacitor configuration
●Significant resonance point shift in high frequency ranges compared to conventional designs
●Optional: ESR optimized design and application temperatures up to +125° C on request.
