Abstract
A switching mode power supply with improved power balance is discussed. It has a transformer, a primary circuit having a primary power switch coupled to a primary side of the transformer, and a plurality of secondary circuits coupled in parallel with each other at a secondary side of the transformer. A plurality of output voltages are provided at each of the secondary circuits; and each of the secondary circuits has a secondary power switch. If any of the output voltage deviates from a reference voltage, an ON time length of the corresponding secondary power switch is extended.
