Power Module Design without Solder Interfaces - an Ideal Solution for Hybrid Vehicle Traction Applications

Hybrid vehicle traction applications require compact power modules with high reliability. A major challenge is the lifetime under thermal cycles. While the requirements are moderate with respect to (active) power cycles, there are challenging requests for a high lifetime under (passive) temperature cycles. Base plates and solder interfaces limit the stability for temperature cycles in the classical module design. Advanced module architecture without base plate and without a single solder interface overcomes the limits of the classical module design and provides an ideal solution for hybrid automotive traction systems.
