In this paper, a new high step-up multi-input-multi output non-isolated dc-dc converter is presented. The proposed converter has dual input and dual output. The benefits of the proposed converter consist of having dual output port, a simple structure, simple control of the power electronic switches and low voltage stress across the semiconductors. In addition, the number of devices of the proposed structure is less than similar topologies. This means by using the same number of devices, the presented topology can generate higher voltage gain in comparison with other structures, which leads to less total cost and complexity. Despite high voltage gain, the normalized peak inverse voltage (NPIVs) on the switches/diodes is low. Conduction losses can be reduced by using the switch with lower resistance r DS(on) . The presented converter is flexible to obtain a high power level with the proper selection of duty cycle values. To confirm the performance of the presented converter, mathematical analysis and experimental results are presented. In addition, a comparison between the presented converter and some other topologies is provided.
