This paper presents steady-state ac analysis of the series resonant converter with phase-
shift and frequency control. Analysis for the converter operation above resonance is
performed. A simple analytical expression for the converter input/output voltage gain as a
function of phase-shift and frequency is derived. Different converter operation modes are
demonstrated with simulation results. Analytical expressions for mode boundaries and
maximum power transfer to load are derived, discussed, and graphically represented.
