DC-Link Capacitors for CISSOID SiC
Intelligent Power Modules-Application Note
General description
CISSOID is collaborating with Advanced
Conversion Inc and NAC to offer high per-
formance DC-Link capacitors mechanically
integrated with our SiC Intelligent Power
Modules (IPMs). These capacitors offer low
ESL and low ESR for fast switching SiC
transistors and for high power density.
Three solutions are available:
- A 6-pack capacitor module mechani-
cally fitting to CISSOID IPMs through a
low inductance busbar. A set of capacitor
values and of voltage ratings is also avail-
able. This solution is best suited for inte-
gration inside an inverter housing.
- A ring capacitor mounted on a busbar
offering low ESL. The busbar is designed
to mechanically fit with CISSOID IPMs. A
set of capacitor values and of voltage rat-
ings is available. This solution is well
suited for first validation tests.
- Custom capacitors can also be de-
signed by Advanced Conversion.
Key features
• Integrated capacitor/busbar solution
• Seamless mechanical integration with
CISSOID Intelligent Power Modules
• Low ESL, typ. 6nH-8nH, for fast
switching with SiC transistors
• Low ESR for high RMS current and
high power density (high A/µF)
• Extreme current pulse survival
• Up to 125°C with PEN film
• Long lifetime: typ. 10.000 hours
• Cooling possible through busbar for
enhanced thermal performance
• Large choice of capacitor values and
voltage ratings with no NRE (standard
parts in stock)
• Custom capacitors available

6-Pack Capacitor Module Test Kit
A 6-pack capacitor module test kit has been developed offering low inductance connection be-
tween the capacitor and the IPM through an optimized busbar. Here also, multiple capacitor
values and voltage rating are available. High temperature film options are also available to
increase the rating.
This capacitor module enables compact design inside inverter housing. The capacitor can also
be flipped to allow cooling through the busbar for improved thermal performance, which can
increase the capacitor rating by a factor of two or more.
These test kits allow for rapid prototyping of the topology without major investments in time and
engineering resources.
