A dynamic model for II-SEPIC (Isolated Inverse-SEPIC) is developed based on the state-space averaging method and its control characteristics are investigated in this paper. Equations for the circuit design of II-SEPIC are derived through the steady state analysis and the resulting circuit parameters are used in the consequent simulation and experiment works. A structure of control system is devised to obtain a better control performance. In order to verify validity and effectiveness of the design equations and the dynamic model, dynamic performances of II-SEPIC system against the line and load variations are investigated in both simulation and experiment. Validity of this paper is also confirmed through the fact that the results obtained from simulation show relatively good coincidence with those from experiment.
