Assessment of the impact of transformer coupling quality on steady state characteristics of series resonant converters

In some applications, for example electric vehicle inductive charger using proximity type inductive coupler, the coupling quality of the transformer could be much lower than an usual isolating/scaling transformer. For such applications it is necessary for the impact of transformer coupling quality on the high frequency inverter stage to be clearly assessed. This paper, on a sound base of steady state analysis, offers the assessment concerning Series Resonant Converter (SRC). The results are given in normalized form and experimentally verified.SCOPUS: cp.p
