Method to balance the secondary winding current to improve the current control stability

A power converter comprising:

• a primary circuit comprising one or more switching elements controllably driven at an operating frequency to produce an alternating current (AC) output through a primary winding of a transformer;
• and
• a secondary circuit comprising:
• first and second secondary windings of the transformer coupled together at a common node, the first secondary winding having a first secondary winding current peak, the second secondary winding having a second secondary winding current peak,
• wherein the secondary circuit configured to provide power across an output capacitor based on a power transfer between the primary winding and the first and second secondary windings;
• and
• at least one balance inductor coupled between the common node and the output capacitor, the at least one balance inductor configured to reduce a difference between the first secondary winding current peak and the second secondary winding current peak, wherein the at least one balance inductor is further coupled between the common node and a ground reference of the secondary circuit.
