Abstract

This paper introduces a new class of adaptive WCCI-based non-inverting step-down/step-up converter that integrates an active Ripple Suppression Engine (RSE) and a dynamic mode-transition controller to simultaneously enhance efficiency and minimize ripple across buck, boost, and buck–boost operating modes. Unlike conventional WCCI ZVT based step-down converters which operate in a single region and rely primarily on passive filtering, the proposed topology employs active current injection and ripple-sensing compensation to reshape the inductor-current waveform and attenuate switching-related conduction losses. With the aid of a dual-threshold window comparator and FSM-based logic, the converter achieves highly stable mode transitions free from ringing, overshoot, or mode oscillation. Simulation results validate the superior performance of the proposed architecture, demonstrating more than a 70% reduction in inductor-current ripple and nearly an 80% decrease in output-voltage ripple compared with the existing work. The converter also exhibits substantially improved transient behavior, achieving faster settling times and significantly lower voltage undershoot during load-step events, all while utilizing smaller passive components. Furthermore, the proposed scheme maintains high efficiency throughout the full 2.5V–8V input range, offering a robust and adaptable alternative to traditional WCCI-based implementations. These findings confirm the suitability of the proposed converter for compact, high-performance power-management applications.
