Abstract :
This paper presents a novel DC-to-DC converter with an auxiliary circuit that completely cancels the ripple current in the output capacitor. Operation principles of the proposed circuit are described, and steady state and small signal ac characteristics are analyzed and confirmed by experiments. Furthermore, a compensation circuit to improve dynamic characteristic is proposed and confirmed by experiments
