Abstract
A back-end energy storage isolation fly-back conversion apparatus (10) includes a return switch (Q1), a driving switch (Q2), an energy storage capacitor (Cs), a transformer (T1), a resonant inductor (Lr), a first rectifier (104), an output capacitor (Cout), and a controller (116). The transformer (T1) includes a primary-side winding (Lm) and a secondary-side first winding (102). The return switch (Q1) is turned on by the controller (116), so that the energy storage capacitor (Cs) is charged by a primary-side current (I1) flowing through the resonant inductor (Lr), the primary-side winding (Lm), and the return switch (Q1), and the secondary-side first winding (102) is powered by the primary-side current (I1). When the primary-side current (I1) becomes negative, the energy storage capacitor (Cs) discharges through the return switch (Q1) and the primary-side winding (Lm) and continuously supplies power to the secondary-side first winding (102).
