“…Generally speaking, the PEMFC could be described as a steady-state model or dynamic model. The steady-state model reflects the relationship between the voltage and current and can be obtained using both analytical and experimental approaches (Arjanaki et al, 2022). The dynamic fuel cell models show the transient performance of the fuel cell by using electrochemical reaction and thermal dynamic equations.…”

This article presents an output power regulation system for micro fuel cells to help enhance the stability of the fuel cell in a portable micro power system. The structure of an MCU-controlled DC-DC converter is proposed. Then, the output characteristics of a selected fuel cell stack and the DC-DC converter’s power control functions are estimated by a system-level model. Based on the simulation results, the model provides a power regulation system which is implemented, and the test shows that it fulfills its intended function and the output power is regulated to a fixed level of 5 W–40 W with good efficiency.

“…A full-bridge boost converter reports 6-10% less efficiency on a comparative basis. As a part of the two-stage DC-DC converter for FC applications, a 1 kW two-inductor boost stage is designed in [57] as depicted in Figure 16. The converter efficiency is about 94% for a 100 kHz frequency of operation, and the output power is 300 W. The conventional isolated converter with N-outputs requires 2 N primary switches.…”

This review emphasizes the role and performance of versatile DC-DC converters in AC/DC and Hybrid microgrid applications, especially when solar (photo voltaic) PV is the major source. Here, the various converter topologies are compared with regard to voltage gain, component count, voltage stress, and soft switching. This study suggests the suitability of the converter based on the source type. The merits of a coupled inductor and interleaved converters in micro gird applications are elucidated. The efficiency and operating frequencies of converts for different operating modes are presented to determine the suitable converters for inductive and resistive loads. The drawbacks of converters are discussed. Finally, the mode of operation of different converts with different grid power sources and its stability and reliability issues are highlighted. In addition, the significance of the converter’s size and cost-effectiveness when choosing various PV source applications are discussed.
