SANDOVAL-IBARRA, F. et al. Analyzing switched circuits to design DC-DC and DC-AC converters. Rev. mex. fís. E [online]. 2007, vol.53, n.1, pp.1-4. ISSN 1870-3542.

The purpose of this paper is to present an alternative analysis of switched circuit to design square wave generators (SWG). A SWG may be designed by using low-cost electronic components, which allows to the readers to understand how DC-DC and DC-AC converters based on the switched approach is an economic option to introduce network analysis concepts. Experimental results show that used techniques allow calculate the frequency range operation not only of the electronic components but also the effect of the power supply value on the generators' performance.
