“…It is important to design the hysteresis band H to impose a steady-state switching frequency in agreement with the physical limitation of the MOSFETs used to construct the dc/dc converter. In Section 3.1, the behaviour of the switching function under steady-state conditions was discussed, and it was summarised in expression (27). Moreover, the correct operation of the SMC imposes the condition v dc = v R , hence the steady-state value of the integral term in (27) is equal to the steady-state value of i L 2 , and the steady-state value of i L 1 is equal to the steady-state value of i L 2 multiplied by 1 − k L .…”

Under the light of the previous analyses, the ripple waveform δΨ of the steady-state switching function is given in (58), in which δv dc represents the ripple waveform of the bus…”

“…Although there are different step‐up/down converters [19, 26] in the literature, buck–boost [9, 12, 14, 18, 27] and sepic/zeta [6, 24, 25] have been used to connect an ESD to a dc bus and to regulate its voltage. However, the zeta/sepic provides some advantages over the buck–boost since, unlike the buck–boost, the zeta/sepic output voltage has the same polarity of the input voltage, and it provides a continuous output current, which reduces the voltage ripples in the dc bus.…”

This study proposes a charging/discharging system of energy storage devices (ESDs) to regulate the voltage of a dc bus. The proposed charging/discharging system is formed by a zeta/sepic converter and a sliding mode controller (SMC). The SMC uses a single sliding surface to regulate the dc bus voltage for the three operating modes of the charger/discharger converter (charging, discharging, and stand-by) and for ESD voltages lower, equal, or higher than the dc bus voltage. This study includes the stability analysis of the SMC and a design procedure of the SMC parameters. The charging/discharging system is simulated in PSIM, where the results confirm that the proposed SMC regulates the bus voltage in charging, discharging, and stand-by modes for different operating points of the system. Finally, the proposed charging/discharging system was constructed for demonstrating the feasibility of the solution for real applications. Moreover, the experimental results obtained in such a platform put into evidence the accuracy of the proposed SMC in regulating the bus voltage in all the possible conditions: bus voltage lower, equal or higher than ESD voltage, and during charge, discharge, and stand-by modes of the ESD.

“…A conventional linear controller is used for the voltage control, and a PWM or a hysteresis controller is used for the current control. The SMC is particularly used for the inductance current control [15,16]. The common design of SMC for the DC-DC buck converters is shown in Figure 5…”

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.
