Abstract

The conventional non-isolated boost converter has some drawbacks such as poor dynamic performance and discontinuous output current, which makes it unsuitable for battery charging application. In spite of its compactness and lightness, it is not preferred for the charger of the portable electronic devices. In this paper, a non-isolated boost converter topology for the Li-Ion battery suitable for fuel cell powered laptop computer is proposed and analyzed. The proposed converter has an additional inductor at the output to make the continuous output current. This feature makes it suitable for the charger application by eliminating the disadvantages of the conventional non-isolated boost converter mentioned above. A prototype of the proposed converter is built for the Li-Ion battery charger of the laptop computer to prove the validity of the proposed topology and its advantages.
