Efficient Silicon carbide (SiC) Technology is central to the design of on-board and off-board chargers in the field of e-mobility. The selection and characterization of suitable products takes a lot of time. In order to be able to implement projects quickly and at the same time to investigate new technologies, Angst+Pfister Sensors and Power (formerly Pewatron) developed the BeFAST Evaluation Kit. It combines low-loss SiC FETs with products optimized for efficient and safe operation into a performance half-bridge. The very low switch-on resistance RDSon  of the SiC Cascoden from United Silicon plays an essential role. The lower switching losses allow faster and more efficient charging.

On the BeFAST Kit, NVE Corp.'s IL7 series products tested according to IEC60747-17 ensure very good isolation of the data to and from the gate driver. In addition to a very long service life, these products also offer high CMTI values. The supply is carried out via a correspondingly approved DC/DC converter of the MGJ2 series from Murata. The Eval Kit is accompanied by a set of different assembled temperature sensors. These very fast analog sensors enable correct monitoring of temperature e.B. during loading and unloading of energy storage systems. The BeFAST can be adapted to the next generation of SiC FET with little effort.
