Integrated IGBT Inverter Modules


SBE Integrated Modules™ are the best way to reduce costs without sacrificing reliability. SBE has been partnering with worldwide leaders such as Danfoss Silicon Power GmbH and Methode Electronics to develop fully integrated sub-system solutions for the power electronics industry.

Power Ring Module™ for 50kW String and Powertrain Inverters

SBE offers Power Ring Module High Density Modules for 50kW – 100kW String Inverters*:
Power Ring Block

  • 100µF at 1100V
  • 220µF at 600V
  • 350µF at 450V
  • PowerBlock - Air cooled

  • Integrated capacitor and laminated bus
  • Shared cooling for IGBT, bus & capacitor (liquid or air cooled)
  • Low ESR < 500 micro-Ω
  • Low ESL < 10nH
  • Modular building block for higher power systems

*IGBT modules and heat sinks sold separately

The Power Ring Module combines the proven Power Ring Film Capacitor attributes of industry leading ESL/ESR and Amps per micro-Farad with its vertically integrated, surface mount, capacitor/bus assembly to maximize power density. The Power Ring Module’s direct, shared cooling of the bus and IGBT provides for cost savings, size reduction and increased performance. The result is a building block for the most power dense, scalable, 50kW inverter possible. At specifications of 100µF/1100Vdc, 600Vdc/220µF, and 450Vdc/350µF the Power Ring Module can easily handle 100 Amps of ripple current. In addition to the Power Ring Module’s unrivaled power density, its extremely low ESL, less than 10nH, allows designers to increase operating voltages without fear of overshoot which would damage the IGBT. The designer is given the ultimate in power density and system scalability.
