  1. Microchip ASD2 IC with configurable augmented switching, DSAT protection, and power supply protection.
  2. Isolated power supply for high side and low side secondary section.
  3. Isolators are provided to isolate gate signals which are transmitted from primary side to secondary side, with a minimum CMTI of 100 kV/μs.
  4. On board continuous pulse train generator circuit, where the pulse width/duty cycle of the waveform can be changed.
  5. On board circuit which can generate two pulses for double pulse testing. The pulse width of the two pulses and the delay time in between can be modified.
  6. Provision for interfacing dsPIC Adapter Board at connector J2 with help of a Sub-Adapter Interfacing Board (AS‑56300‑SUB).
  7. Provision for selecting signals source—Double Pulse Test (DPT) section or continuous pulse generator.
  8. LED indications provide various fault and power ON status.
  9. Provision to interface external NTC and characterize temperature related feature of ASD2.
  10. Power Device (SiC MOSFET) mounted on the Heatsink.
  11. Provision for measuring current at high side and low side devices using a Rogowski Coil.
  12. Provision for measuring current by using a shunt resistor with help of BNC connector.
  13. Provision of connecting Negative Voltage Bus Terminal (–VBUS).
  14. High Voltage bulk capacitors (66 µf\F).
  15. Provision for connecting to the Positive High Voltage Bus Terminal (+VBUS), accepts up to 1200V with respect to Negative Bus terminal (–VBUS).
  16. Provision for Monitoring High Voltage.
  17. Heatsink for power device (SiC MOSFET).
  18. Provision for selecting PWM signal coming from dsPIC Adapter or on board generated PWM signal.
  19. Programming header for primary side controller.
  20. Test-point for monitoring various signal (monitoring connector J2 signals).
  21. Provision for interfacing external push-button for generating double pulse signal.
