In previous era, coal and oil like non‐renewable resources were mostly used for power generation, thus causing a severe environmental problem as well as high economic. An intelligent maximum power point tracking (MPPT) system was proposed to overwhelm the above‐mentioned impacts, which tracks the maximum generation of photovoltaic (PV) under various atmospheric conditions. Moreover, a modified DC‐DC converter was introduced to low inrush current and switching oscillation. The proposed model working process was split into three steps: first, design the normal PV with a grid‐integrated power system. Second, create a dataset with the aid of a designed PV model, and finally, design an intelligent MPPT controller based on that dataset. The difference among the MPPT and PV voltage was fed to an optimal controller that generates an appropriate pulse signal of the modified DC‐DC converter. The proposed intelligent tracking system was analyzed under various circumstances like static, dynamic and combined shading conditions. The proposed model offers 99.5% efficiency and very low harmonics values like 0.15% current total harmonic distortion (THD) and 0.46% voltage THD. The outcome verifies that the intelligent MPPT approach performs well than that of the currently used controllers in solar power generation and conditioning systems.

SummaryMulti‐input converters (MICs) play a significant role in the aspect of the integration of sources. The reliability of the converter can be enhanced by using a suitable fault tolerance converter design and control algorithm. A dual‐input single‐output (DISO) DC–DC converter with source fault tolerance is proposed in this paper. In the literature, there are many topologies in this area of work; however, most of them are based on time‐sharing control. In this control scheme, one input source is contributed to the load, and others are kept idle in a particular duty interval; hence, this control scheme leads to underutilization of the converter. The proposed converter is designed to circumvent these challenges and can produce boost, buck–boost, and buck operations. And also, it has a source fault feature for achieving the preserved output voltage under source V1 or V2 failure conditions. A 200‐W prototype is designed, and the feasibility of the proposed converter is validated through simulation and experimental results.

“…Previous model-based techniques, on the other hand, are susceptible to system characteristics and have limited detection accuracy [73]- [75]. Prior knowledge regarding converter specifications (parasitic resistances, inductances, capacitances) is critical for the improvement of model-based algorithms, but difficult to gain from the existing system [16], [44], [76]. Shahbazi et al [49] proposed a model-based approach for detection of fault using a field-programmable gate array (FPGA) based on time and voltage criteria.…”

<p>The dependability of power electronics systems, such as three-phase inverters, is critical in a variety of applications. Different types of failures that occur in an inverter circuit might affect system operation and raise the entire cost of the manufacturing process. As a result, detecting and identifying inverter problems for such devices is critical in industry. This study presents the short-time Fourier transform (STFT) for fault classification and identification in three-phase type, voltage source inverter (VSI) switches. TFR represents the signal analysis of STFT, which includes total harmonic distortion, instantaneous RMS current, RMS fundamental current, total non harmonic distortion, total waveform distortion and average current. The features of the faults are used with a rule-based classifier based on the signal parameters to categorise and detect the switch faults. The suggested method's performance is evaluated using 60 signals containing short and open circuit faults with varying characteristics for each switch in VSI. The classification results demonstrate the proposed technique is good to be implemented for VSI switches faults classification, with an accuracy classification rate of 98.3 percent.</p>
