“…Distinction between CM and DM in three-phase systems has been carried out in several previous works, mostly in three-wire systems [20], [27], [28]. In a few studies, this decomposition is performed in four-wire lines, but exclusively to study the behavior of CM, whose definition may vary [29], [30]. In summary, an agreement cannot be found in the literature on the more convenient definition, from an EMC perspective, of propagation modes for three-phase systems.…”

“…The associated drawback is a variable switching frequency that depends on the states of the system [36]. Moreover, the electromagnetic compatibility (EMC) issues resulting through the variable frequency pose additional design challenges [37][38][39]. Therefore, it is necessary to achieve a fixed switching frequency in SMC because power converters are composed of reactive components, and their accurate design is frequency dependent, thereby making it an active area for research [40][41][42].…”

Fuel cells guarantee ecological ways of electricity production by promising zero emissions. Proton exchange membrane fuel cells (PEMFCs) are considered one of the safest methods, with a low operating temperature and maximum conversion efficiency. In order to harness the full potential of PEMFC, it is imperative to ensure the membrane’s safety through appropriate control strategies. However, most of the strategies focus on fuel economy along with viable fuel cell life, but they do not assure constant output voltage characteristics. A comprehensive design to regulate and boost the output voltages of PEMFC under varying load conditions is addressed with dynamic integral sliding mode control (DISMC) by combining the properties of both the dynamic and integral SMC. The proposed system outperforms in robustness against parametric uncertainties and eliminates the reaching phase along with assured stability. A hardware test rig consisting of a portable PEMFC is connected to the power converter using the proposed technique that regulates voltage for varying loads and power conditions. The results are compared with a proportional integral (PI) based system. Both simulation and hardware results are provided to validate the proposed technique. The experimental results show improvements of 35.4%, 34% and 50% in the rise time, settling time and robustness, respectively.

“…However, the variable switching frequency is not acceptable for power converters because it causes electro-magnetic compatibility (EMC) issues along with complicating the design for its suppression. [14][15][16] Hence, fixing the switching frequency in SMC is an active research topic in the field of power electronic converters. 17,18 Interesting results are reported for phase shifted fullbridge converters, 19 interleaved buck converters 16 , current control of permanent-magnet synchronous machines, 20 cascaded boost converters 21 and AC-DC converters.…”

The key characteristics of the sliding mode control (SMC) are the ability to manage unmodeled dynamics with rapid response and the inherent robustness of parametric differences, making it an appropriate choice for the control of power electronic converters. However, its drawback of changing switching frequency causes critical electro-magnetic compatibility and switching power loss issues. This paper addresses the problem by proposing a dynamic integral sliding mode control for power converters having fixed switching frequency. A special hardware test rig is developed and tested under unregulated 12.5-22.5 V input and 30 V output. The experimental findings indicate excellent controller efficiency under wide range of loads and uncertain input voltage conditions. In addition, the findings indicate that the closed-loop system is robust to sudden differences in load conditions. This technique provides an improvement of [Formula: see text]% in the rise time, [Formula: see text]% in the settling time and [Formula: see text]% in robustness of the controller as compared to conventional controllers. Furthermore, the comparison with the existing fixed-frequency sliding mode control techniques is presented in a tabular form.
