2.4.2.8 LLC Secondary-Side Currents

The total secondary-side RMS load current is the current referred from the primary-side current to the secondary side.

Equation 39.

Because the secondary side of the transformer has a center-tapped configuration, this current is split equally into two transformer windings on the secondary side. The current of each winding is then calculated as:

Equation 40.

The corresponding half-wave average current is:

Equation 41.
