“…The steady state voltage gain of a power electronic converter can be obtained using the fundamental volt second balance method applied to the voltage across the inductor or by using the state space model [23][24][25]. These studies help to get an insight into the open loop characteristics of the converters and also help to design closed loop controllers as well.…”

In this work, a novel, high boost, DC-to-DC converter topology is proposed and validated. The proposed topology is an extension of the existing two leg bridge type Watkins Johnson DC to DC converter. In the proposed system, an additional leg is included along with an additional inductor and an additional capacitor. The inclusion of the third leg to the existing, two-leg version of Watkins Johnson DC-to-DC bridge type converter helps to boost further the voltage gain. This paper presents the proposed topology and a detailed analysis of the topology using the circuit model in the MATLAB SIMULINK simulation environment. An experimental prototype was also developed to validate the proposed idea. The results obtained from the simulations and the experimental prototype are also presented herein. The studies were carried out with open loop configuration.

“…There is a need for a versatile power conversion system that can efficiently adjust the variable or fixed input DC voltage to the required value, especially in the context of solar energy. While conventional converters such as Boost, Buck or Buck-Boost configurations have been widely used, they come with significant drawbacks [5][6][7][8]. These include pulsating input and output power, high switching losses, fabrication costs, and rating restrictions.…”

Power converters are widely used in renewable energy conversion systems such as photovoltaics. Their main role is to adapt the output voltage to a desired voltage shape.This study proposes a highly efficient Single-Ended Primary Inductor Converter (SEPIC) to enhance the utilization of PV arrays by ensuring a continuous flow of current. To minimize DC voltage ripples, a Proportional-Integral (PI) controller is presented to continuously monitor the High power extracted from the PV array. The PI controller parameters are optimized using the Osprey Optimization Algorithm (OOA), which mimics the hunting behavior of ospreys in nature. The OOA draws inspiration from the hunting strategy of ospreys when they hunt fish in the seas. The osprey first detects the position of its prey and then captures it, carrying it to a suitable location to consume it. Similarly, the OOA iteratively optimizes the PI controller parameters to advance the SEPIC converter and achieve a DC-link voltage for steady-state at the converter's output. Then it is fed into a voltage source inverter (VSI), which connects the system to a single-phase utility grid. A fuzzy logic tuned PI controller is employed to synchronize the inverter's output with the grid. The performance is evaluated by analyzing the harmonic content in the grid current. To validate the proposed approach, a Simulink model is developed and compared against a hardware prototype. The proposed results achieved an effectiveness of performance and efficient power conversion in the system.

“…The main obstacle in the development of solar power plants is the investment cost of the photovoltaic system. Besides that, because the efficiency of solar power plants is very low in the range of 9 -17% in areas with low irradiation [2]. In addition to low irradiation, the efficiency of the photovoltaic system is also influenced by environmental factors such as temperature, solar radiation illumination, humidity and the inappropriate position of the photovoltaic module to the earth [3].…”

The efficiency of the photovoltaic system is very low ranging from 9-17% in areas with low irradiation while the investment costs are quite high. In addition, the power output of the photovoltaic system is highly volatile due to changes in irradiation due to weather and cloud movement, and temperature change. This research proposes the MPPT method based on ANFIS in the photovoltaic system for transient behavior analysis and system efficiency improvement. The results of the proposed method were compared with the MPPT Perthub & Observe (P&O) method. Each MPPT method was applied to a boost converter connected to a photovoltaic module with a capacity of 150 Wp to adjust the duty cycle using Simulink simulation in MATLAB. The irradiation and temperature data for 3 consecutive days were from Saturday to Monday, September 4 to 6, 2021. The simulation results show that the transient time of ANFIS MPPT is 6.23 times faster than that of P&O MPPT. The efficiency of ANFIS-based MPPT is higher than MPPT P&O. At 917.3 W/m2 of irradiation, the output power of the boost converters are 132.09, and 111.69 Watt for the ANFIS-based MPPT controller, and the P&O method MPPT, respectively.
