The work is devoted to the study of performance a multilevel electric energy converter using phase-shifted pulse-width modulation. Equations describing state dynamic system - load are investigated and mathematical model in Matlab / Simulink environment has been constructed. Variants implementation modulation systems from point view influence on harmonics output voltage magnitude circulating cur...

This paper reviews and discusses the state of art integrated switched-capacitor inductive power converters provides a perspective on progress towards realization efficient fully DC–DC conversion. A comparative assessment has been presented to review salient features in utilization transistor technology between switched inductor converter-based approaches. First, applications that drive need for...

We have proposed a novel driving concept for TFT-OLEDs, pulse-width modulation with current uniformization. This driving method can simultaneously achieve precise grayscale and exceedingly improve luminance uniformity. Lately, we succeeded to reduce the number of TFTs in a pixel circuit from nine to seven. Especially in this paper, its working and tolerance against characteristic deviations of ...

For the first time the influence of noise amplification on decay of modulated continuous-wave pumping into a pulse series in an optical fiber is considered. Dependence of noise-to-signal ratio in pulse train at fibre exit on initial modulation depth obtained both analytically and by means of numerical simulations. The minimum modulation frequency is estimated which leads to a regular pulse trai...
