3.1 Output Current Ripple

The ripple current of this design was tested on the output capacitors with different phase shifting. The following list shows the primary current of each phase and the ripple current in output capacitors, with 0 degree shift and 90 degree shift.

  • Channel 1, is the primary current of phase A
  • Channel 4, is the primary current of phase B
  • Channel 3, is the ripple current on the output capacitors
