As it was mentioned in the first part, this paper is focused on the nonlinear behavior of the DC-DC converters. The Buck converter was chosen to apply different tools in order to analyze the stability of operation under voltage and current control. Also, besides the qualitative information given by the graphical methods used, the performances of the control techniques are evaluated in time and frequency...
With the ever increasing complexity of the high speed digital and analog design both time and frequency analyses are to be considered. The present paper presents a brief overview on linear and nonlinear simulations type and evaluation of the effects of choosing transient or harmonic balance in evaluation of interconnections on a printed circuit board by using eye diagram tool.
This paper focuses on the theoretical and experimental analyzes on the dynamics of a magneto-piezoelectric pendulum system under the magnetic excitation. Initially, it handles the theoretical modelling of the problem including the mechanical, magnetic and electrical terms of the system. The theoretical formulation of the pendulum system is realized based on the experimental parameters. Then, a detailed...
This paper propose the use of “Proportional-Resonant” (PR) controllers for Power Factor Correction (PFC) circuits used in front-end converters for grid-connected applications. The performance of the PFC converter with PR control is analyzed using simulations and the advantages and disadvantages of this kind of control are discussed. The classical PI controllers and the PR controllers are evaluated...
