“…The inherent buffeting of the sliding-mode control is simultaneously weakened and even eliminated in a few cases. Matlab simulation and Opal RT based experimental analyses prove that the proposed sliding-mode control with an MPAL features significant advantages unlike the traditional slidingmode control and provides a certain practical value [30].…”

“…These topologies couple an impedance network between the inverter and power source. In these converters, shoot through state also known as overlap-mode switching state is defined as both switches are intentionally made turned on while controlling the boosting of the input voltage by the amount of time within shoot-through time [17], [18], [19]. This quasi-Z source inverter (qZSI) topology possesses a simple impedance network and switches are not connected ahead of inductor branches.…”

The Z-source inverter (ZSI) topology replaces multiple stages into a single stage in power conversion so it is going to be an appropriate topology for 1-phase grid-connected PV system. In this paper, the various z-source topologies are discussed as available in different literature. This paper has proposed a proportional and integral (PI) Controlled bridged grid-connected solar photovoltaic (PV) network for electrical vehicle charging. The different modulation techniques applied in these topologies have been described. The bridged grid-connected network equipped with solar modules can prove effective in developing charging infrastructures for electric vehicles (EVs) at residential or commercial complexes. The different parameters of this suggested topology may vary during different time instants of a whole day at different modes of procedure i.e solar PV generation to the grid, EV to grid, and both PV and EV to grid. The simulation work has been done with the PWM technique to obtain battery voltage and grid voltage, Fast Fourier Transform, and total harmonic distortion.

“…Sliding mode control defines a sliding surface to guide the system's state onto it and applies a control law to achieve stable control of the system, exhibiting strong robustness and disturbance rejection against uncertainties and disturbances. It has extensive applications, particularly in dealing with uncertain complex nonlinear systems and photovoltaic inverter systems (Rezkallah et al, 2015;Chen et al, 2019;Ortega et al, 2019). The sliding mode control method based on the exponential reaching law further improves this technology (Fallaha et al, 2011;Wang and Wei, 2019).…”

Photovoltaic inverters are widely utilized in microgrid systems working as the key equipment for converting solar energy into usable electricity. This paper presents a fuzzy sliding mode control (FSMC) method for the photovoltaic inverter in a microgrid. The inverter module uses voltage control to achieve stable AC output voltage. Moreover, to deal with system uncertainty and non-linearity in the photovoltaic inverter, a fuzzy controller was designed to realize real-time adaptation of the gains of the constant term and the reaching term in the sliding mode control law, which serves as a compensating controller for traditional sliding mode control. The gains of the exponential reaching law can be adjusted according to the system state instead of fixed gains, which can effectively reduce the chattering phenomenon and improve the robustness of the photovoltaic microgrid. Finally, the Lyapunov stability theory was used to ensure the stability of the entire control system, achieving a high-performance independent power supply for loads in a microgrid. Simulation results show that the designed control system is more robust to load disturbances and has superior dynamic performance.
