Infineon starts volume production of first full-SiC-module

Higher efficiency, increased power density, smaller footprints and reduced system costs: these are the main advantages of transistors based on silicon carbide (SiC). Infineon Technologies is starting volume production for the EASY 1B, the first full-SiC module announced during PCIM 2016. On the occasion of this year’s PCIM in Nuremberg, the company is showcasing additional module platforms and topologies for the 1200 V CoolSiC MOSFET family. Infineon is now able to bring the potential of SiC technology to a new level.

The new 1200 V SiC MOSFETs have been optimized to combine high reliability with performance. They show dynamic losses which are an order of magnitude lower than 1200 V silicon IGBTs. First products will initially support upcoming system challenges in applications such as photovoltaic inverters, uninterruptible power supplies and charging/storage systems. The new configurations will also enable revolutionary new solutions in industrial drives, medical technology or auxiliary power supplies in the railway sector in the near future.

One major advantage of the trench technology with the 1200 V SiC MOSEFT lies in an extended robustness. This is due to the lower failure in time (FIT) rate and the short-circuit capability, which can be adapted to the respective application. Thanks to a threshold voltage (V th) of 4 V and the recommended switch-on threshold (V GS) of +15 V, the transistors can be controlled like an IGBT and safely switched off in the event of a fault. The SiC MOSFETs enable very fast switching transients. In addition, Infineon’s technology offers an easy adjustability of the transients via gate series resistors. The EMC behavior can thus be easily optimized.

Already last year, Infineon announced the lead products EASY 1B (Half-Bridge / Booster) as well as the discrete TO-247-3pin and -4pin solutions. The EASY 1B platform is well established and an ideal module platform for fast switching devices. At this year’s PCIM fair, Infineon will be exhibiting additional module platforms and topologies based on the 1200 V SiC MOSFET technology. This extends the performance spectrum of the CoolSiC MOSFETs step by step.
