Abstract  This paper aims to investigate the step-down dc-dc converters from circuit analysis viewpoint. These converters have a lot of utilizations, including different applications in power energy conversion domain, being mentioned also in electromagnetic compatibility studies.That is why the study and the analysis of such devices were and continue to be of a real interest for the scientific community. For this … Continuă lectura Analysis of a Step-Down DC-DC Converter: Linear Versus Nonlinear Circuit
