Sampled-Data Modeling and Analysis of PWM DC-DC Converters I. Closed-Loop Circuits
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 i...

Chauhan, Shweta. M.S.Egr, Department of Electrical Engineering, Wright State University, 2014. Hysteretic controlled DC-DC converters. Switched-mode DC-DC converters are widely used in applications requiring stepup and step-down of DC voltages or currents. These converters find their use in portable applications such as laptops and smart phones, radio-frequency power amplifiers, as light emitti...
متن کاملSampled - Data Modeling and Analysis of PWM DC - DC Converters Part II
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...
متن کاملSampled-data modeling and analysis of one-cycle control and charge control
Sampled-data modeling and analysis are applied to PWM dc–dc converters under one-cycle control or its special case, charge control. These two control schemes are analyzed in a unified framework. Large-signal analysis, steady-state analysis and small-signal analysis are addressed analytically. The orbital nature of the nominal periodic solution is preserved. Various transfer functions are derive...
متن کاملPWM and PFM Operation of DC/DC Converters for Portable Applications
This topic discusses the trade-offs between fixed-frequency pulse-width modulation (PWM) and pulsefrequency modulation (PFM) for portable DC/DC converter applications. PWM converters offer the benefit of predictable operating frequency, which may simplify the design of circuitry that suppresses electromagnetic interference (EMI). They also offer low output ripple characteristics and high effici...
