Abstract :
In this paper, a nonlinear control algorithm for a current-fed DC-DC is presented. This converter consists of an inductor, a controllable full-bridge converter, which is connected to a full-bridge rectifier via a high-frequency transformer. The advantages of this converter include galvanic isolation, high voltage gain and low input current ripple. Based on Flatness properties, we proposed a controller, which can guarantee the responses during either start-up or steady-state. The experimental results are obtained for validating the proposed control method.
