This paper proposes a solution to complement the insufficient voltage gain and voltage stress distribution of classicalinterleaved boost converter in high step-up application. An interleaved converter integrating coupled inductor and voltagemultiplier cell, which provides an additional voltage gain is proposed. By stacking the secondary side of the interleaved coupledinductor to its primary side, a high step-up voltage gain and distributed voltage stress are realised. Low-voltage rated devicesultimately reduce the conduction losses. The principle of operation and the performance characteristic of the converter arepresented and verified by an experimental prototype of 140 W, 12 V input, and 120 V output.
