Modelling of a Buck converter with adaptive modulation and design of related driver stage

This thesis concerns the modelling of a buck converter with peak current mode control, and adaptive PWM/PFM (constant Ton) and provides a small signal model, derived from steady-state averaging, for all the operative regions of the converter, and used for stability analysis and parametric optimization. Eventually the design of a driver stage is proposed, with segmentation, dead time control and zero cross detection as main functionalities to improve efficiency
