Large signal analysis using discrete time domain modeling for LCC-Type parallel resonant converter operating in discontinuous current mode

A discrete time domain model for the LCC-type parallel resonant power converter, operating in discontinuous current mode (DCM) has been derived. All the equations representing the discrete time domain model are given. This model, which makes use of some practical approximations, simplifies the calculations, reduces the computer simulation time and is adequate to predict some of the basic design constraints (peak component stresses etc.), which are governed by the dynamics of the converter during transients. PRO-MATLAB software was used to implement the discrete model on the computer. SPICE results are included to verify the analytical results. All the results are verified experimentally and the results are included
