Abstract

A low ripple or ripple free input current boost converter operating in continuous inductor current mode is very desirable in industry. In this paper, a new modified boost converter is proposed and analyzed. Compared to the conventional boost converter, the new boost converter can achieve ripple free input current by using coupled inductor techniques. Compared to the Cuk and Sepic converters, the new boost converter has several advantages which may result in a high efficiency. The small signal model of the new boost converter is analyzed. A comparison between this circuit and several alternatives is presented. The predicted theory is verified experimentally
