Sampled-Data Modeling and Analysis of PWM DC-DC Converters I. Closed-Loop Circuits
نویسندگان
چکیده
General block diagram models are proposed for PWM DC-DC converters in continuous and discontinuous conduction modes with fixed switching frequency. Both current mode control and voltage mode control are addressed in these models. Based on these models, detailed nonlinear and linearized sampled-data dynamics are derived. Asymptotic orbital stability is analyzed. Audio-susceptibility and output impedance are derived. In this approach, discontinuous conduction mode and current mode control can be analyzed systematically without special effort. A companion paper [1] addresses the same issues for the power stage of a PWM DC-DC converter.

The power stage of the PWM DC-DC converter is modeled and analyzed using the sampleddata approach. This work complements the companion paper [1] which develops sampled-data models and analysis for the closed-loop converter. Separate models for the power stage are essential for controller design. The work addresses continuous and discontinuous conduction mode under voltage mode control, and cont...

A major problem in an isolated DC/DC converters operating at high switching frequencies is the attendant switching losses in the semiconductor devices. This can be reduced by introducing either zero-voltage switching (ZVS) or zero-current switching (ZCS) of the semiconductor switches. This paper deals with the simulation, design, fabrication and experimental evaluation of a novel soft-switching...
