3.3 Start-Up Sequence

PMP23338 Test setup Figure 3-1 Test setup

Start-up sequence:

  1. Check GaN card, C2000 control card and Bias card are plugged in correctly and tightly
  2. Use a fan for cooling during test
  3. Connect a high voltage load to DC output, set load to 0.1A
  4. Connect AC source to AC input
  5. Use current probe to monitor AC input current, use voltage meter to measure DC output voltage
  6. Set AC output at 115V/60Hz, turn on AC, you see DC output voltage is regulated at about 385V
  7. Graduate increase load. Full load: 1800W@115VAC, 3600W@230VAC
