Within the present trend towards miniaturization and higher power densities, smaller passive components together with higher switching frequencies are desired. In combination with new market requirements there is an upcoming trend for resonant converters with inductive output filter (e.g. LED drivers). But since it is rather difficult to design reasonable high inductance values for the output coils, the assumption of a constant current source at the output is not justified in most cases. As a consequence, this paper introduces a novel, detailed analysis of the series resonant converter incorporating finite values for the output inductance. To the authors' knowledge, it is the first time that the influence of its finite value is included in the investigation of this converter.
