Fast Short-Circuit Protection of SiC-MOSFETs through AC Current Sensors – A Perfect Fit for Highly Efficient Electrical Drives
- Using special ac current sensors, it was shown that short-circuit protection of the latest CoolSiC™ MOSFET technology is possible. This simplifies the use of CoolSiC™ MOSFETs in applications such as industrial drives, where a certain robustness against short circuits is required. The use of CoolSiC™ MOSFETs leads to a more efficient drive inverter, which can help to reduce the energy costs over lifetime. In addition, the CoolSiC™ MOSFET enables inverter integration into the motor, which is challenging with state-of-the-art IGBTs. Furthermore, fast short-circuit protection can also help to increase the efficiency of an IGBT-based inverter by increasing the gate voltage.
