“…However, one of the satisfactory features of the classic boost converter is related to its current continuity with an appropriate ripple, which has been weakened in some of the new boost structures. Due to low voltage of DC-based RESs [20][21][22][23][24][25][26], their voltage must be increased to the required value without ignoring the essential voltage quality. That is to say, some DC-based RESs are connected in series to each other to obtain a high-level voltage, if so, it is inevitable to meet the high cost-price and complicated control circuits.…”

As for the insufficient nature of the fossil fuel resources, the renewable energies as alternative fuels are imperative and highly heeded. To deliver the required electric power to the industrial and domestic consumers from DC renewable energy sources like fuel cell (FC), the power converter operates as an adjustable interface device. This paper suggests a new boost structure to provide the required voltage with wide range gain for FC power source. The proposed structure based on the boost converter and the quazi network, the so‐called SBQN, can effectively enhance the FC functionality against its high operational sensitivity to experience low current ripple and also propagate voltage and current with low stress across its semiconductors. Furthermore, the switching power losses have been decreased to make this structure more durable. A full operational analysis of the proposed SBQN and its advantages over the conventional and famous structures has been compared and explained. Furthermore, a prototype of the single‐phase converter has been constructed and tested in the laboratory.

“…The deep and major drawbacks of such these converters are their large size inductor, high peak inverse voltage on switches, high total cost, low electrical energy efficiency and unqualified output voltage. Due to low voltage of DC-based RESs [20][21][22][23][24], their voltage must be increased to the required value without ignoring the essential voltage quality.

As for the insufficient nature of the fossil fuel resources, the renewable energies as alternative fuels are much needed and highly heeded. To deliver the required electric power to the industrial and domestic consumers from DC renewable energy sources like Fuel Cell (FC), the power converter operates as an adjustable interface device. This paper suggests a new boost structure to provide the required voltage with wide range gain for FC power source. The proposed structure based on the boost converter and the quazi network, so-called SBQN, can effectively enhance the FC functionality against its high operational sensitivity to experience low current ripple, and also propagate voltage and current with low stress across its semiconductors. Furthermore, the switching power losses have been decreased to make this structure more durable. Full operational analysis of the proposed SBQN and its advantages over the conventional and famous structures has been compared and explained. To more evaluate the high-step up voltage capability of the proposed SBQN and validate the simulations results, a prototype of the single-phase converter has been constructed and tested in the laboratory.
