Abstract
In this study, a new high step-up dc–dc converter is proposed. The proposed converter has two switches that operate in two operational modes. In the first case, both switches are turned on simultaneously, where the voltage gain would be similar to cascaded boost converter but the input current ripple will not be removed. Thus, the high voltage conversion ratio can be achieved with a suitable duty-cycle. In this case, the performance of the converter has been investigated in two continuous and discontinuous conduction modes. In the second case, two switches operate inversely. In this case, in addition to having high voltage conversion ratio, the input current ripple is removed by a pre-selected duty cycle. The results of the steady-state operation of the converter are studied in both discontinuous conduction mode and continuous conduction mode. Finally, a 100 W prototype of the proposed converter has been implemented in the laboratory for evaluating its performance.
