It’s showing the overall operation of motors with solid slitted rotor given better rotor construction. These are used in whole circuit heating induction heavy materials, highest frequency control. The power of high frequency controlling maintains and developed high speed with 3 phase capacitor of motors. The 2-pole, 3-phase, 180 kW, 150 Hz high rated motors with solid slitted rotor is designed in RMxprt, Ansys software.Its mechanical parts showing cycloinverter fed 2-pole, 3-phase, 180 kW, 150 Hz highest controlling speed of motor is compared with the cycloinverter fed a conventional three phase 50Hz induction motor. These are showing the induction motors speed, which are we can varied in a ways, first is changing by frequencies and second is changing by the no. of poles. The cycloinverter fed speed of induction motors gives better operating torque which are numerically analyzed that average operating torque is 23 % more than that obtained from cycloinverter fed conventional 50 Hz motors.

The iteration scheme is analyzed as a multivariate discrete time propagation of nonlinearly coupled equations, which is dictated by only a few principal cluster amplitudes. These principal amplitudes usually correspond to only a few valence excitations, whereas all other cluster amplitudes are enslaved and behave as auxiliary variables [Agarawal et al., J. Chem. Phys. 154, 044110 (2021)]. We develop a coupled cluster-machine learning hybrid scheme where various supervised machine learning strategies are introduced to establish the interdependence between the principal and auxiliary amplitudes on-the-fly. While the coupled cluster equations are solved only to determine the principal amplitudes, the auxiliary amplitudes, on the other hand, are determined via regression as unique functionals of the principal amplitudes. This leads to significant reduction in the number of independent degrees of freedom during the iterative optimization, which saves significant computation time. A few different regression techniques have been developed, which have their own advantages and disadvantages. The scheme has been applied to several molecules in their equilibrium and stretched geometries, and our scheme, with all the regression models, shows a significant reduction in computation time over the canonical coupled cluster calculations without unduly sacrificing the accuracy.

New recommendations and future standards have increased the interest in power factor correction circuits; a review of the most interesting solutions for single phase and low power applications is carried out. They are classified attending to the line current waveform, energy processing, number of switches, control loops, etc. The major advantages and disadvantages are highlighted and the field of application is found.

From the past few years, resonant converters obtained more and more attention. In this research mathematical representation is a little fiddly. So we are chosen a method for simplifying this calculation, which is very fetching like first switching circuit and second is one resonance tank. While a steady-state solution for these methods might be acceptable or too close for an expected solution, then with a simplified solution we have predicted zero voltage switching characteristics is disrepair or making simple. We know that zero voltage switching characteristics with all focused directly related to the voltage transfer function results which are too positive approximated to the obtaining of range operation zero voltage switching. Therefore, in this paper focuses on a more accurate investigation of the resonant LLC converter's zero voltage switching behaviour and proposed approximation methods, which ar...

CQDs have the desirable advantages of low toxicity, environmental friendliness, low cost, photostability, favorable charge transfer with enhanced electronic conductivity, and their comparable easy synthesis protocols. This article examines advancements in CQD research and development, with a focus on their synthesis, functionalization, and energy applications. Initially, various synthesis methods are discussed briefly with pros and cons. Herein, first top-down methods including arc discharge technique, laser ablation technique, plasma treatment, ultrasound synthesis technique, electrochemical technique, chemical exfoliation, and combustion were discussed briefly. The later section presents bottom-up (microwave synthesis, hydrothermal synthesis, thermal pyrolysis, and MOF template-assisted approach) and waste-derived CQDs synthesis methods. The next section is focused on the energy applications of CQDs including supercapacitors, lithium-ion batteries, photovoltaics, hydrogen (HER), and oxygen evolution reaction (OER). Finally, challenges and perspectives in this exciting and promising area are presented.
