3Dynamic Modeling of Direct-on-Time Control

3.1 Introduction

This chapter provides the unified basis for the average and small-signal modeling of voltage-fed switched-mode converters under direct-on-time (DOT) control in continuous (CCM) and discontinuous (DCM) conduction modes [1]. In case of fixed switching frequency, the control mode will be referred as direct duty ratio (DDR) control, because the same dynamics associated with the on-time is also present in the duty ratio (i.e., ). If the switching frequency is varying, then the dynamic modeling has to be performed applying the DOT control method, because the duty ratio is then a nonlinear ...
