This paper reports the modeling and simulation aspects of a peak current controlled power-factor-correction converter (PFC), which is widely used in switch-mode power supply applications. The main objective is to show the real behavior of this converter operating under specific conditions. Firstly, a numerical simulation based on a discrete model is used. Analysis of this model shows that chaos and...
Highly detailed models of power converters can be slow to simulate due to the wide disparity in transient time scales. This is further pronounced in the presence of nonlinear components, e.g., saturated inductors. Variable-resolution simulation provides an alternative method by providing an appropriate amount of detail based on the time scale and phenomenon being considered. First, a high-fidelity...
Recently, power factor correction (PFC) boost converters have been reported as exhibiting a wide range of bifurcations and chaos under specific conditions. In this paper, we derived a nonlinear model from one point of observation to the next. Analysis of this model shows that chaos and bifurcations may occur along with the changing values of some system parameters. A current-mode controlled PFC boost...
Micro-wind turbines incorporating permanent magnet synchronous generators are among the suitable power sources for telecommunication equipment especially in remote areas. Average-value modeling is indispensable for large- and small-signal analysis of such machine-converter systems. However, analytical derivation of accurate models is challenging particularly at low voltage applications due to the...
