Note:
  1. 180A per phase at 15V, 2700W for 10s with a 20s break.
  2. Paralleled PSFB DA boards uses droop control with 12V battery attached.
  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 control system of the converter includes various protections, as listed in Table 1-4. All protection points and recovery points may have ± 1% accuracy due to hardware, such as resistors and an operational amplifier.
