3.1.1 Hardware

The DUT in this design is set up and operated in several pieces:

  • One TIDA-010210 mother board (TIDA-010210-MB-E2)
    • J75 Header : Jumper between pin 1 and pin 2
    • Change 750344413 with 750343810 (L2, L4, L6)
  • Six TIDA-010210 power cards based on GaN (TIDA-010210-GaN-E3)
  • Three TIDA-010210 power cards based on Si (TIDA-010210-Si-E2)
  • TMDSCNCD280049C Control Card:
    • S2 Switch : Change from the DOWN to the UP position
    • S3 Switch : Changed from the UP to the DOWN position
  • Mini USB cable
  • Laptop or other computer

The test equipment required to power and evaluate the design is as follows:

  • >12-V, 2-A bench style supply for primary board power
  • >11-kW AC source
  • >11 kW, 800-V DC load
  • > 1000-V, 10-A power supply for DC link input
  • > 6.6-kW resistive AC load
  • Four-channel power quality analyzer
