“…The interference engine uses the legislation for fluid input in order to determine the fluid outputs. Therefore, the crimped input levels must be fluctuated before the rules can be evaluated [16] in order to obtain the appropriate language values and the degree to which every portion of the precedent was satisfied with every rule. Tables.2 show a table of Table.2 shows.…”

Solar energy is act clean as well as renewable source of energy. Hence the use of PV systems has used in many applications. Big-spread use has resulted in decreased solar panel production expenses. But the low effectiveness of a solar panel owing to variables such as solar insulation, clouds and shading impact continues one of the greatest issues. Due to variable concentrations of isolation, the panel output remains variable during cloudy weather. To increase the solar panel's efficiency, the maximum algorithm for power point tracking needed as it was discovered only a small percentage of the energy incident is transformed into electricity. DC-DC Converter (Boost Converter) design helps to increase the panel output, thereby improving effectiveness and output voltage using reasonable control technique. This article discusses the development of the fluctuating MPPT logic control to track the maximum output point and also to compensate for fluctuating power during cloudy weather. The suggested primary circuit block diagram. The simulation study is carried out and the proposed circuit is implemented by hardware. MATLAB Simulink is used for simulating the circuit.

This paper presents an application of a multi-cell resonant boost converter as an MPPT device for solar PV off-grid systems. The paper also presents the comparison of the theoretical efficiency of a multi-cell resonant boost converter with a traditional boost converter used as an MPPT or high gain boost devices for solar PV – battery backup off-grid AC systems on various factors such as power, duty cycle, and frequency. It is concluded that a multi-cell resonant converter improves the system's overall efficiency by Zero Current Switching (ZCS). Furthermore, an energy management scheme is proposed for power generation management. The energy management scheme performs the following tasks: regulate power generation by MPP and non-MPP mode of operation, regulate power consumption by battery charging current control and load shedding, and ensure power supply to baseload (lean power demand). MATLAB 2021a is used for the simulation, and dSPACE DS1104 based controller is employed to run the experimental prototype. The simulation and experimental prototype results are presented to validate the theoretical concepts. The paper concludes that the multi-cell resonant boost converter is efficient, and performs successfully at various power regulation tasks therefore, the multi-cell resonant boost converter is a better choice over a traditional boost converter for solar-PV off-grid systems.

“…For multi‐input converters, most of the work has been devoted to phase‐shifted full bridge converters. In Reference two identical current fed full‐bridge converters are connected in parallel to interface a common output rectifying diode‐bridge but sharing an integrated transformer. The two current fed bridges are controlled in a phase‐shifted manner.…”

This paper proposes a low voltage (400 Vdc) distributed renewable energy fed DC microgrid structure for a residential system, which uses DC voltage for the electronic appliances. The distributed energy sources—solar photovoltaic (PV) and wind energy are considered as input sources. The output power from these sources is stochastic in nature. An efficient energy management and switching circuit is designed to control the power flow from the sources with a high gain DC‐DC converter as the main component. The output power regulation is achieved by means of controlling duty ratios of the switches in the proposed high gain converter through PI controller. The control algorithm effectively converts the unregulated DC power from the solar PV and wind into regulated DC for driving a DC load connected in DC‐microgrid. The energy management and switching circuits account for seamless operation of the DC microgrid under various modes when one or all the sources and loads are connected directly at the DC grid link. The designed energy management and switching circuit also ensures the power balancing in the proposed system. The proposed DC microgrid structure is simulated using MATLAB Simulink. The performance of the proposed high gain converter for the DC grid link voltage regulation is analyzed under source power variation and dynamic changes in load for various operating conditions. The proposed DC microgrid structure is validated using simulation results.
