Operating characteristics of discontinuous current conduction mode in DC-DC buck converter

摘要

It is well known that DC-DC buck converters, which are used in electronic apparatuses as power sources, show nonlinear vibrations and chaos depending on the setup condition. In this paper, the operating characteristics are discussed experimentally and numerically, especially in its discontinuous current conduction mode which is used to be avoided in the practical use. Moreover the parallel connection of the converters is tested for sharing the load in its nonlinear operation.
