Rheinmetall’s NanoLam™ capacitors represent a leap forward in the realm of power management for inverters, charging systems, and DC-DC conversion. These capacitors boast a higher capacity density and higher temperature stability with ideal package options while maintaining very low inductivity.

Positioned directly upstream of the inverter, our DC-Link Capacitor acts as a short-term energy buffer for the traction motor. This design is critical in managing the fluctuating current demands that the distant battery cannot promptly adjust to.

Furthermore, the versatility of our capacitors is underscored by their adaptability, being equally effective when utilized in on-board chargers, DC-DC converters, or auxiliary drives, thereby ensuring seamless and efficient energy conversion across various applications.

Benefits

• A novel production process, based on the parallel deposition of metal and dielectric system in situ.
• Production process allows for ultra-thin layers with less restrictions, gaining direct advantages in terms of capacitance density and ohmic losses.
• The use of acrylic plastic as dielectric material, which provides advantages in:
  • terms of dielectric constant (εR=3.2)
  • breakdown voltage
  • temperature resistance
  • thermal conductivity
  • oxygen content for improved self-healing capabilities.
• The rectangular shape achieves a high package utilization, and allows for busbar structures with favorable cooling properties and low parasitic loop inductances.
