Abstract

The buck converter is a widely used switched converter to adapt a higher DC voltage to a lower DC voltage. In the conventional design, the converter has two reactive elements, an inductor and a capacitor. Replacing these dynamical elements by a transmission line results in a distributed buck converter. Modeling the transmission line by the telegrapher's equations yields a model with completely new properties. We investigate the behavior of this system and present a practical circuit realization.
