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