Abstract

In this paper, a novel voltage-bucking/boosting converter, named as KY buck-boost converter (i.e. 2D converter) is presented herein. Unlike the traditional buck-boost converter, this converter possesses fast transient responses, similar to the behavior of the buck converter with synchronous rectification. In addition, it possesses non-pulsating output current due to this converter always operating in the continuous current mode (CCM), thereby not only decreasing the current stress on the output capacitor but also reducing the output voltage ripple. The proposed converter is illustrated in details and some simulation and experimental results are provided to demonstrate the effectiveness of the proposed topology.
