摘要：

A new input-output coupled inductor (100) is proposed for reducing current ripples and magnetic components. Moreover, a current-source-type circuit using active-clamp mechanism and a current doubler with synchronous rectifier are presented to achieve high efficiency in low input-output voltage applications. The configuration of the 100 is realized by three windings on a common core, and has the properties of an input inductor at the input-side and two output inductors at the output-side. An active clamped ripple-free dc-dc converter using the proposed 100 is analyzed in detail and optimized for high power efficiency. Experimental results for 80 W (5 V/16 A) at a constant switching frequency of 100 kHz are obtained to show the performance of the proposed converter.
