“…Figure 2 shows the block diagram representations of six distinct MPPT methods. The first five MPPT methods are frequently reported in the literature [12][13][14][15][16][17][18][19][20] and the last one is the proposed method. In the constant voltage method [6,15], the voltage at the MPP is established to the STC ( MPP(STC) ) and the voltage across the PV module ( PV ) is compared to this value, through…”

This paper presents a new maximum power point tracking (MPPT) method based on the measurement of temperature and short-circuit current, in a simple and efficient approach. These measurements, which can precisely define the maximum power point (MPP), have not been used together in other existing techniques. The temperature is measured with a low cost sensor and the solar irradiance is estimated through the relationship of the measured short-circuit current and its reference. Fast tracking speed and stable steady-state operation are advantages of this technique, which presents higher performance when compared to other well-known techniques.

“…Another widespread method is the open-circuit voltage [14,18]. This method uses the open-circuit voltage ( OC ) to estimate the MPP by means of a constant (between 0.7 and 0.8), which is related to the MPP .…”

“…However, this approach suffers from huge voltage spikes caused by the transformer's leakage inductance, resulting in power loss in the switch. Thus, non-isolated BDCs [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25] are chosen over isolated BDCs due to their various advantages, such as their higher efficiency, greater reliability, and lower component count, which leads to a smaller size and lower overall cost [5,6]. In general, a high duty cycle is used to achieve high gain in transformerless converters.…”

“…Furthermore, the reliability of the switches is harmed as a result of the high voltage stress caused by the high duty ratio. To address these concerns, other converter topologies have been proposed in the literature, including coupled inductors in typical boost topologies [11][12][13][14], cascading converters [15] and interleaved topologies [9,10,16,17] to alleviate voltage spikes. Coupled inductor (CI)based topologies have received the most attention as they can achieve high conversion gains due to their compactness and high power density in both charging and discharging modes [18][19][20][21][22].…”

A step-up for a non-isolated interleaved differential capacitor clamped boost (IDCCB) DC–DC converter is proposed in this manuscript. Because of its ability to produce high voltage gains, it is used in high-power applications. This converter’s modelling and control design are applicable to any number of phases. A six-phase interleaved differential capacitor clamped boost prototype is tested in this work, with an input voltage of 60 V, an output voltage of 360 V, and a nominal output power of 2.2 kW. The components of the converter are placed and controlled in such a way that the output voltage is the sum of the two capacitor voltages and the input voltage, which is two times higher than the supply voltage when compared to a conventional interleaved differential dual-boost converter. This converter reduces the stress on the capacitor with reference to the conventional interleaved differential boost converter for the same conversion gain. This prototype is considered and the developed approach is applied, after which the experimental results are obtained. This converter has potential for application in areas such as renewable energy conversion and electric vehicles.

“…Such non-linear and non-minimum phase characteristics further confuse the MPPT of the boost converter [5]. To overcome these problems, different conventional and intelligent MPPT algorithms have been proposed such as Incremental Conductance (IC) [6][7][8], Open Circuit Voltage (OCV) [9], Short Circuit Current (SCC) [10], Perturb and Observe (P&O) [11], fuzzy logic [12][13][14][15], feedback linearization [16], neural network [17][18][19][20][21][22], neuro-fuzzy [23][24][25] and sliding mode [26,27]. Nevertheless, there still remains the concern of fast and accurately determining the locus of the MPP during high weather variations and external load changes occurring.…”

An intelligent control of photovoltaics is necessary to ensure fast response and high efficiency under different weather conditions. This is often arduous to accomplish using traditional linear controllers, as photovoltaic systems are nonlinear and contain several uncertainties. Based on the analysis of the existing literature of Maximum Power Point Tracking (MPPT) techniques, a high performance neuro-fuzzy indirect wavelet-based adaptive MPPT control is developed in this work. The proposed controller combines the reasoning capability of fuzzy logic, the learning capability of neural networks and the localization properties of wavelets. In the proposed system, the Hermite Wavelet-embedded Neural Fuzzy (HWNF)-based gradient estimator is adopted to estimate the gradient term and makes the controller indirect. The performance of the proposed controller is compared with different conventional and intelligent MPPT control techniques. MATLAB results show the superiority over other existing techniques in terms of fast response, power quality and efficiency.
