Unified Subharmonic Oscillation Conditions for Peak or Average Current Mode Control
Chung-Chieh Fang
This paper is an extension of the author's recent research in which only buck converters were analyzed. Similar analysis can be equally applied to other types of converters. In thi…
Discrete-Time Poles and Dynamics of Discontinuous Mode Boost and Buck Converters Under Various Control Schemes
Chung-Chieh Fang
Nonlinear systems, such as switching DC-DC boost or buck converters, have rich dynamics. A simple one-dimensional discrete-time model is used to analyze the boost or buck converter…
Analysis and Control of Period-Doubling Bifurcation in Buck Converters Using Harmonic Balance
Chung-Chieh Fang, Eyad H. Abed
Period doubling bifurcation in buck converters is studied by using the harmonic balance method. A simple dynamic model of a buck converter in continuous conduction mode under volta…
Local Bifurcations in DC-DC Converters
Chung-Chieh Fang, Eyad H. Abed
Three local bifurcations in DC-DC converters are reviewed. They are period-doubling bifurcation, saddle-node bifurcation, and Neimark bifurcation. A general sampled-data model is e…
Modeling and Instability of Average Current Control
Chung-Chieh Fang
Dynamics and stability of average current control of DC-DC converters are analyzed by sampled-data modeling. Orbital stability is studied and it is found unrelated to the ripple si…
Saddle-Node Bifurcation Associated with Parasitic Inductor Resistance in Boost Converters
Chung-Chieh Fang
Saddle-node bifurcation occurs in a boost converter when parasitic inductor resistance is modeled. Closed-form critical conditions of the bifurcation are derived. If the parasitic…
