Steady state and generalized state space averaging analysis of the series resonant converter

This paper proposes a generalized state space averaging modeling instead of using the small ripple hypothesis to obtain the small signal modelling for the resonant converter. As well, this work covered the investigation of both the steady state analysis and the generalized state space averaging modelling effectively for the series resonant converter worked under zero voltage switching conditions. The proposed method and the steady state of the converter are analysed and simulated using MATLAB SIMULINK. It was found that the transfer function of the voltage by controlling the duty ratio D can make the needs of the control possible.
