Tapped-inductor step-down converter and method for clamping the tapped-inductor step-down converter

摘要

A tapped-inductor step-down converter and method for clamping same with a clamping capacitor so that MOSFETs can be employed to improve circuit efficiency. The converter includes a tapped-inductor and clamping capacitor uniquely arranged to eliminate resonance between the leakage energy of the leaky inductance and the clamping capacitor. Moreover, such arrangement provides for the recycling or recovering of the leakage energy from a leaky inductance of the tapped-inductor to further improve circuit efficiency.
