frequency to retain the triangular shape of the inductor current. It will be assumed in the following, therefore, that.the output signal of amplifier A, includes a remnant of the inductor current triangular waveform (except for possible curvature of the corners) multiplied by a constant (kJ. In CM realisation (Fig. 2), the output of the error amplifier V;, modified by a 'compensation slope' Mc ...

The paper is related to the problem of generating the high quality AC voltage waveforms using multilevel converters. This technique can be applied especially in the distributed power energy systems with renewable DC voltage sources like photovoltaic farms and fuel cells. A novel approach to the synthesis of AC voltage waveforms, applying analytical methods like Fourier transform and Haar wavele...

Automated vehicles are becoming popular across the communities of e-transportation globe. Hybrid electric and autonomous have been subjected to critical research for decades. The outcomes pertinent this topic in literature motivated by industry researchers emphasize automated vehicles. Part 1 survey addressed aspects that concern bidirectional converter topologies condition monitoring activitie...

analysis of time series data can involve the inversion of large covariance matrices. for theclass of arma (p, q) processes there are no exact explicit expressions for these inverses, except for thema (1) process. in practice, the sample covariance matrix can be very large and inversion can becomputationally time consuming and so approximate explicit expressions for the inverse are desirable.thi...

Industries are heavily dependent on fossil fuels. Considering their swift dwindling rates, the motive to seek and adopt alternatives has taken charge. The sun its solar energy is one such alternative source of energy, which generally regarded as rich actually “free”. generation electricity from sunlight using photovoltaic convertors most widespread mature technology for harvesting energy. In sp...

let and be a sequence with non-negative entries. if , denote by the infimum of those satisfying the following inequality: whenever . the purpose of this paper is to give an upper bound for the norm of operator t on weighted sequence spaces d(w,p) and lp(w) and also e(w,?). we considered this problem for certain matrix operators such as norlund, weighted mean, ceasaro and copson matrices. th...
