This paper proposes a design of a high step-up DC/DC converter is presented for Renewable Energy Applications. The suggested structure consists of a coupled inductor and two voltage multiplier cells in order to obtain high step-up voltage gain. In addition, two capacitors are charged during the switch-off period using the energy stored in the coupled inductor which increases the voltage transfer gain. The energy stored in the leakage inductance is recycled with the use of a passive clamp circuit. The voltage stress on the main power switch is also reduced in the proposed topology. Therefore, the main power switch with low resistance RDS can be used to reduce the conduction losses. The operation principle and the steady-state analyses are discussed thoroughly. To verify the performance of the presented converter, a laboratory prototype circuit is implemented. The results validate the theoretical analyses and the practicability of the presented high step-up converter. These converters boost the low input voltages (24-40 V) to a high voltage level(300-400 V). The simulation will be carried in MATLAB/SIMULINK and results will be presented to validate the claim.
