Mosfet overcurrent protection
Webrespond faster to overcurrent faults and provides better current-limit accuracies. However, many of the discrete circuit-protection realizations have the following shortcomings which limit their wider usage: • Discrete circuits use P-MOSFET as pass FET, which is more expensive than N-MOSFET to achieve the same ON resistance (RDS(ON)). WebFeb 1, 2024 · SC event may occur in some power electronics systems and the overcurrent protection circuits could protect SiC MOSFETs from destruction under SC condition, so the degradation of SiC MOSFETs under repetitive SC stress becomes crucial for the reliability of the industrial application.
