Hybrid Silicon Carbide Power Modules

Power Modules with IGBTs and Silicon Carbide Schottky Diodes

Hybrid Silicon Carbide Power Modules: higher efficiency, easy to implement

Semikron Danfoss offers hybrid Silicon Carbide power modules in MiniSKiiP, SEMITOP, SEMITRANS, SEMiX and SKiM 93. The latest IGBT technology is combined with SiC Schottky diodes from leading suppliers to increase the switching frequency and reduce power losses at the same time. Thanks to the minimal changes required in the system design, hybrid SiC power modules are an easy way to benefit from the features of Silicon Carbide. The hybrid Silicon Carbide power modules are available from 50A to 600A in 1200V in sixpack, half-bridge and chopper topologies.

SiC Schottky freewheeling diodes have virtually no switching losses and reduce the turn-on losses of the IGBT drastically. In combination with standard or high-speed IGBTs, higher switching frequencies can be achieved in the same module package. This efficiently lowers the filter needs on the output side, for example, of solar inverters, UPS systems or high frequency power supplies. Higher output powers than with standard silicon power modules can also be achieved, interesting for motor drives.
