Infineon Technologies SSCB Evaluation Kit

Infineon Technologies Solid-State Circuit Breaker (SSCB) Evaluation Kit allows easy evaluation of AC- and DC-type circuit breakers with the help of an interactive GUI. This kit supports 110VAC, or 230VAC, or 350VDC operation and a 16A nominal current. It can support different SSCB topologies like 1P - N, 3P - N (stacked, cascaded), L+ - L-. The Infineon Technologies SSCB Evaluation Kit features non-isolated integrated coolers mounted over top-side cooling (TSC) SiC MOSFET packages to support passive cooling.

Features

  • Floating switch - Back-to-Back (B2B) power MOSFET configuration for bidirectional current blocking capability
  • Passive cooling with Top-Side Cooling (TSC) concept - Cu heatsink soldered over the MOSFET
  • External user interface bus in Safety Extra-Low Voltage (SELV) domain - high-speed CAN and digital inhibit input
  • Isolated backplane communication bus (for multichannel configuration) in Functional Extra-Low Voltage (FELV) domain - UART and bidirectional digital I/O signal
  • Protection and monitoring provisions
    • Shunt resistor-based channel current measurement
    • Shunt resistor-based overcurrent detection (OCD)
    • Isolated channel input and output voltage measurement
    • Temperature close to source pin (Tntc) measurement by NTC
    • Overload (OVL), overtemperature (OVT), undervoltage (UVP), and overvoltage protection (OVP)
  • F-RAM for data logging
  • Programmability and monitoring with SSCB Demo graphical user interface (GUI)
    • AC or DC operation selection
    • Positive and negative OCD trip thresholds
    • Overtemperature shutdown and recovery thresholds
    • UVP and OVP thresholds
    • Trip chart parameters - nominal current, static overdrive factor, fast and slow overcurrent factors, and tripping integral
    • In-application programming to calibrate the channel input and output voltage and current
    • Monitoring and export of analog measurements like VIN, VO, I, f, P, power factor, OCD threshold references, Tj or TNTC
  • TFT display to monitor V, I, P, f, Tj or TNTC, SSCB state, and diagnostic information
  • Self-powered - flyback power supply from grid, no external supply needed
