چکیده :

In this paper, a high gain DC-DC boost converter is proposed. The proposed converter utilized the switched-inductor-capacitor LCD network technique to achieve high voltage gain. One of the merits of this converter is that it can reach higher voltage gains with less than 50 percent duty ratios. The proposed converter includes two inductors, three capacitors, five diodes, and two semiconductor switches which work simultaneously. Although there are two switching devices, the control signal is not complicated since the switches work synchronously and only need one controlling signal. The operation principle of the converter is analyzed in continuous conduction mode. The proposed converter results are verified by a 60W laboratory prototype.
