In this paper, a developed structure is proposed for High Step-up Non-Isolated Non-Coupled Inductor based Multi-Port dc-dc converters. The voltage gain per number of devices of proposed topology is higher than that of similar topologies. This means that, by using the same number of devices, the proposed topology can generate higher gains than other structures. In other words, the proposed topology utilizes less number of devices for producing the same voltage gain, which leads to less total cost, size, weight and complexity. Despite high voltage gain, the Normalized Peak Inverse Voltage on switches/diodes is low. Higher number of input ports leads to higher gains and lower NPIVs on devices. The load energy can be absorbed and stored in first input unit. Modularity, simple structure, continuous input currents and low input current ripple are the other profits of proposed topology. Low/medium power applications are suggested for proposed structure. Proposed topology has been explained and operational modes along with steady state analysis have been discussed. For better verification, proposed topology has been compared with several multi-port high gain converters. Comparison results confirm the advantages of proposed topology. Finally, the proper performance of proposed topology has been validated by experimental results.

A new three‐phase hybrid multilevel inverter configuration is proposed. The proposed inverter is modular and consists of three single‐phase H‐bridge inverters, one three‐phase H‐bridge inverter and auxiliary modules for increasing the number of output voltage levels. The performance of the proposed inverter has been compared with some of the commonly used inverters within the literature in terms of the number of components, blocking voltage and overall losses. The proposed multilevel inverter has lower number of insulated‐gate bipolar transistors and gate drivers and subsequently requires a relatively simple control strategy for generating the desired output voltage. Finally, the performance of the proposed inverter has been validated via a laboratory‐scale prototype along with numerical simulation.
