FCAS50SN60

Overview

The FCAS50SN60 is a smart power module designed for single-phase Switched Reluctance Motor (SRM) drives. It integrates a 600V-50A asymmetric bridge IGBT converter with control ICs for gate driving and protection. The module features very low thermal resistance due to Direct Bonded Copper (DBC) technology. It includes divided negative DC-link terminals for inverter current sensing, allowing separate monitoring of each phase current. A built-in High Voltage Integrated Circuit (HVIC) enables opto-coupler-less gate driving and supports single-grounded power supply topologies.
