“…Presented in [65] is an interesting study on interconnecting fuel cells to obtain maximum output power. Two interconnection techniques; namely, i) modular integrated converter (MIC) and ii) differential power processing (DPP) including their power converters (synchronous switching bidirectional buck-boost) and EMS technique (MPPT P&O / Hill Climbing (HC)) were modeled using Matlab and discussed in details.…”

Fuel Cells (FCs) and Combined Cooling, Heating and Power (CCHP) systems are becoming very popular due to their environmental friendliness and immense applications. This extended review paper commenced by introducing the rampant South Africa's electricity crisis as the basis for the study, followed by some structural analyses of up to forty-four miscellaneous power electronics converters case studies applicable to fuel cells including at least sixteen FCs energy management systems (EMS) applicable case studies. The review rationale is to determine innovative best practices that can be applied to devise an efficient power converter and EMS for an energy efficient FC CCHP system. From these analyses, it is realized that each power converter and EMS scheme has its merits and demerits depending on the targeted applications and most importantly the research project objectives − that is, whether the goals are to reduce costs, enhance efficiency, reduce size, boost performance, simplicity, durability, reliability, safety etc. Therefore, the conclusion drawn is, there is no "one size fits all" approach, as all the various reviewed case studies reported relatively good results based on their chosen schemes for their targeted applications. Notwithstanding, this review highlights are, i) the interleaved boost converter and variants as well as ii) the maximum power point tracking (MPPT) technique; are the most widely used schemes, as they are reasonably effective and simple to implement. The contributions brought forward are i) an apt single reference study that presents a quick topological insight and synopsis of assorted FCs power converters as well as EMS and ii) our proffered FC CCHP system undergoing research to offer an innovative energy efficient solution for basic household energy needs such as electricity, heating, cooling and lighting.

“…Figure 5 shows the differential power processing architecture applied to a centralized TEG structure. In the case presented here, a non-isolated architecture has been used among the different sub-modules that make up the TEG system [18]. Differential converters are connected to the TEG cells to balance the current flows between the different sub-modules.…”

This paper presents a Differential Power Processing (DPP) architecture applied to series-connected thermoelectric generators (TEG). Currently, thermoelectric technology is being considered as a promising power generation technology that can be used to recover waste heat energy. Thus, a thermoelectric generation system is studied under non-uniform temperature conditions in multiple TEG devices. The main objective is to allow each thermoelectric sub-module to reach its maximum power point more quickly. The purpose has been to improve the maximum power point tracking (MPPT) in each sub-module, thus it is possible to increase the efficiency with respect to the traditional method based on a global MPPT. Differential Power converters have been implemented in each TEG sub-module to provide an effective solution and mitigate the impact of the mismatch in the power obtained. The DPP architecture consists of a small micro-converter, at the submodular level, applied to the thermoelectric cell. The control algorithm is oriented to polarize each TEG device at its optimal point, which allows us an active balancing among the different TEG sub-modules regardless of the operating temperature. Matlab-Simulink has been the software used to develop the TEG module-array.
