“…The PID current controller C 1 (s) and voltage controllers C 2 (s) and C 3 (s) have been tested experimentally and have given the following responses: A decimation phenomenon affects the six Figures 18-23. This is due to the 4-channel digital oscilloscope used to record the values of the current and the voltage in the experimental test bench (see 13 ○ in Figure 17). However, this decimation phenomenon does not act on the closed loop behavior since the record with the 4-channel digital oscilloscope is outside the closed loop.…”

“…Usually, a DC-DC converter is required to couple the PEMEL to the RES. Given that the PEMEL requires a low rated voltage (roughly equal to 8 V [13]) to maximize the production of hydrogen from water electrolysis, DC-DC buck converters are commonly used for this purpose [14,15,16]. However, depending on the electrical grid and the feature of the PEMEL, different DC-DC converter topologies can be employed [13,17].…”

Nowadays, the proton exchange membrane electrolyzer (PEMEL) is a promising and attractive technology when coupling with renewable energy sources (RES). Indeed, PEMEL can respond quickly to the dynamic operations of RES. Given that PEMEL must be supplied with a low DC voltage, DC-DC converters are mandatory. In this work, a stacked interleaved buck DC-DC converter is used. In this paper, the tuning of proportional, integral and derivative (PID) controllers, which are often used to enhance electrolyzer performances (efficient and reliable operation), is based on the dynamic behavior of the PEMEL. Before designing the PID controller, a model of the PEMEL is proposed based on input-output measured data, and this model is combined with the converter state-space description. Then, the obtained global model is used to tune two PID controller configurations: the first one to control the current and the second one to control the voltage of the PEMEL. Experimental tests are carried out to validate the effectiveness of the designed control laws.

“…It is worth discussing that we have contemplated this interconnection rather than using "dummy" laboratory setup. The results would be further relevant to comprehend, and the converters' efficiency would be contained under real-time PV operating conditions, rather than using an indoor programmable load [10]- [12].…”

The main objective of the article is to provide a thorough review of currently used AC-DC converters for alkaline and proton exchange membrane (PEM) electrolyzers in power grid or wind energy conversion systems. Based on the current literature, this article aims at emphasizing the advantages and drawbacks of AC-DC converters mainly based on thyristor rectifier bridges and chopper-rectifiers. The analysis is mainly focused on the current issues for these converters in terms of specific energy consumption, current ripple, reliability, efficiency, and power quality. From this analysis, it is shown that thyristors-based rectifiers are particularly fit for high-power applications but require the use of active and passive filters to enhance the power quality. By comparison, the association combination of the chopper-rectifier can avoid the use of bulky active and passive filters since it can improve power quality. However, the use of a basic chopper (i.e., buck converter) presents several disadvantages from the reliability, energy efficiency, voltage ratio, and current ripple point of view. For this reason, new emerging DC-DC converters must be employed to meet these important issues according to the availability of new power switching devices. Finally, based on the authors’ experience in power conversion for PEM electrolyzers, a discussion is provided regarding the future challenges that must face power electronics for green hydrogen production based on renewable energy sources.
