Dynamics of the capacitive-loaded push-pull parallel-resonant converter: investigation by a SPICE compatible average model

An average model of the capacitive-loaded push-pull parallel-resonant DC-DC converter (CL-PPRC) was developed and applied to study the static and dynamic behavior of the CL-PPRC. The model is compatible to SPICE and can also be used to derive analytical expressions for the static and small signal dynamic responses. It was found that the dynamics of a CL-PPRC, operating in the continuous (input) inductor current mode, is similar to that of a boost converter operating in discontinuous mode.<
