Abstract

This paper presents a current controller and voltage balancing for a current-fed full-bridge converter, we have chosen this converter, which is an interleaved boost `like´ converter connected with a voltage doubler rectifier at load side via a high-frequency transformer. The advantages of this converter are: high voltage gain, low ripple input current and galvanic isolation. With the proposed controller, the voltage across the output serial capacitors was balanced. The experimental results validate the proposed control method.
