Abstract
Peak primary current control on the secondary side. In a power converter having a primary side and a secondary side separated by a main transformer, example methods include: driving primary current through a primary winding of the main transformer; creating, on the secondary side of the main transformer, a signal indicative of current through the primary winding of the main transformer; and ceasing the driving of primary current through the primary winding when the signal indicative of primary current reaches a predetermined value.
