“…These high currents naturally cause some loses on the components. Some solutions are proposed to reduce loses in different papers, therefore we will not focus on this matter in this paper [10,12]. Only a selection of elements with low losses will be sufficient.…”

This paper focuses on two different scenarios to benefit from solar energy more efficiently. One of them is photovoltaic houses and storing their energy as hydrogen, the other one is photovoltaic cars and storing their energy as hydrogen. The common point in these two photovoltaic sourced scenarios is convert and storage of the hydrogen energy more efficiently. The direct current (DC) photovoltaic energy is converted to the desired voltage level using the DC-DC buck converter for generating hydrogen with electrolysis process. The electrolysis load for hydrogen production needs low voltage and high currents especially. To supply these conditions the converter must be designed and controlled sensitively. For this aim, the sliding mode controller is proposed as a solution in this study. This controller is used the inductance current in the inner loop and supply a strong control for the converter under normal and abnormal conditions. The photovoltaic powered DC-DC buck converter for electrolysis load was simulated in MATLAB/ Simulink software more detailed using the sliding mode controller.

“…A FLC for full-bridge soft switching converter is designed and verified in [26]. A DC-DC converter is proposed in [27] for solar energy-hydrogen conversion system and as the electrolysis load is nonlinear, FLC is a choice in place of other linear controllers. In [14,28] digital design and hardware implementation of FLC using DSP is demonstrated.…”

“…Hence, it leads to the novel and systematic approach of humanistic intelligent system. It controls the system using simple if-then rules such that the input variable lies within the membership values (Takagi and Sugeno, 1985;Arulselvi and Uma, 2014;Mattavelli et al, 1997;Sahin and Okumus, 2014). FLC is simulated by using the fuzzy toolbox provided in the MATLAB.…”

Multiport DC-DC converters have been most commonly used in stand-alone renewable power systems to provide smooth and constant power to the loads. To supply the load without any interruption under various disturbances, the centralised controller in various typologies of multiport converter has been implemented only by using conventional proportional integral (PI) controller. This study presents the output voltage control of the three-port full-bridge converter interfacing photovoltaic (PV) system with three different controllers. The dynamic response of the proposed converter is analysed with the PI controller, fuzzy logic controller (FLC), and the sliding mode controller (SMC). The state space model of the three-port full-bridge converter is developed to analyse the performance using SMC. PI, FLC, and SMC-based control scheme is developed using the MATLAB/Simulink environment. The response of the PI, FLC, and SMC are analysed for line regulation, load voltage regulation, and for the converter parameter variation. The simulation results illustrate that the SMC gives a better steady state and dynamic response when compared with the PI and FLC. The results are presented to confirm the proposed control schemes.Keywords: power converter; fuzzy control; PI control; renewable energy sources; sliding mode control; state-space methods.Reference to this paper should be made as follows: Mahendran, V. and Ramabadran, R.
