Innovative step‐up direct current converter for fuel cell‐based power source to decrease current ripple and increase voltage gain

Abstract

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.

Design principles of voltage controlled DC-DC boost converters through the integration of PID and model predictive control

“…Different control techniques are used for different types of converters. The fractional-order controller for a boost converter can provide enhanced regulation of the output voltage based on fractional calculus principles [16,17]. The use of an Internal Model Control (IMC) strategy for a boost converter involves designing a controller that includes an internal model of the system dynamics.…”
