Impact of QSW‐ZVS on Input EMI Filter Design in DC‐DC Converters

International Journal of Circuit Theory and Applications, EarlyView.
This paper analyzes the impact of quasi‐square wave zero voltage switching (QSW‐ZVS) on passive EMI filter design for DC‐DC buck converters. The extra element theorem (EET) is used to derive the design quantities that ensure converter performance is not altered, and the resulting damping element values are compared with those of traditional converters.

Thevenin Equivalents of Some Interesting Networks with Dependent Sources [PDF]

IETE Journal of Education, 2014
ABSTRACTThis paper presents two classes of networks whose Thevenin equivalents are interesting. One class of networks is without any independent source. The other class has loop or node method-based delta 0. If proper care is not taken, then their Thevenin equivalent resistances may result in indeterminate forms.
