Notification 673 – SR AUX output in AC Stack

CATEGORY

ISSUE / RESULT

FIX / REFERENCE(S)

Error

Unable to configure a second synchronously rectified output as part of an AC stack.  An AC stack can only contain a single SR output.  The winding on the second SR output (auxiliary SR) should only be floating, not part of the same AC stack.

Reconfigure the transformer outputs so that the main SR is in the main output and is part of the AC stack.  Configure the winding of the second (auxiliary) SR output as floating.
