A Non-Insulated Step-Up/Down DC-DC Converter with Wide Range Conversion

In this paper an approach of a step-up/down dc-dc converter with wide range conversion called Boost2-Buck is presented. The proposed converter presents nonpulsating input and output current. It has operations equivalent to a cascade converter consisting of two boost converter and one buck converter, but with the advantage of using single active switch. Mathematical analysis and experimental results are presented for converter operating with output power of 20W.
