SANDOVAL-IBARRA, F; MERCADO-MORENO, J.R  e  URIOSTEGUI-VAZQUEZ, L.H. Basic circuits to design switched-based DC-DC converters. Rev. mex. fís. E [online]. 2007, vol.53, n.2, pp.128-133. ISSN 1870-3542.

The purpose of this paper is twofold. On one hand, basics on switched circuits for designing a DC-DC converter are presented and, on the other hand, power electronics definitions associated with simple electrical networks are mentioned. In the analysis of these networks, it is necessary to take into account not only converters' non-idealities but also how to minimize power losses. Since power losses may be minimized by increasing the clock frequency of switched-based converters, experimental results of basic clock generators are presented. These generators were implemented with low-cost components
