摘要

art I. A unified model is established for a current-programmed converter, which unifies and extends previous models. A low-frequency modification leads to a unified duty-ratio control law for the buck, the boost, and the buck/boost converters. Inclusion of the sampling effect allows the presence of an additional pole ;Part II. A generic averaged model for switches in dc-to-dc converters is established for the first time by using, in addition to averaging, volt-second and amp-second balance equations. Switches in dc-to-dc converters can now be handled as linear-time-invariant two-terminal circuit elements for their low-frequency characterizations. A theoretical discussion about the equivalent duty ratio
