Note:
  1. 180A per phase at 15V, 2700W for 10sec with 20 sec break.
  2. Paralleled PSFB DA boards using droop control.
  3. Demo code operates at 100 kHz.

The outer dimensions of the board, without the aluminium base plate, are 310 mm x 135 mm x 37 mm.

The converter’s control system includes various protections. All protection points and recovery points may have ± 1% accuracy due to hardware, such as resistors and operational amplifier.
