Sampled-Data Modeling and Analysis of PWM DC-DC Converters Under Hysteretic Control
Abstract
The PWM DC-DC converter in continuous conduction mode under hysteretic control is modeled and analyzed using the sampled-data approach. This work complements other recent work of the authors on sampled-data modeling and analysis of PWM converters, where the focus was on fixed switching frequency operation. Nonlinear and linearized sampled-data models, and the control-to-output transfer function are derived. The analysis is exact if the source and reference signals are constant (or constant within each cycle).
