چکیده
The parasitic effects in stranded, twisted, and Litz wire windings operating at high frequencies are studied. The skin and proximity effects tha t cause the winding parasitic resistance of an inductor t o increase with the operating frequency are considered. An expression for the ac resistance as a function of the operating frequency is given. The measured and calculated values of the inductor ac resistance and quality factor are plotted versus frequency and compared. The theoretical results were in good agreement with those experimentally measured.

The paper presents unified modeling and analysis of high-power-factor rectifiers based on switching converters with nonlinear-carrier control (NLC). In NLC control, which offers simple, high-performance power-factor correction (PFC), the switch duty ratio is obtained by comparing a signal derived from the switch current with a periodic nonlinear carrier. A general expression is derived for the ...

A nonlinear model for zero-current-switch quasi-resonant-converters is proposed which can be derived easily using simple analytical techniques. It is readily accepted by MATLAB for analysis and simulation in fast speed. Simulations have shown its accuracy even for large-signal transient dynamics. The condition for zero-current switching is also identified from this model.
