A NOVEL UNIFIED MODELING METHOD FOR DC/DC SWITCHING CONVERTERS BASED ON COMPUTER-AIDED ANALYSIS

摘要

A new approach to model resonant converters, was presented in the paper. The variant sub-topologies of a converter are unified into an equiualent topology by the periodic pulse function, Laplace transforms of the sampled function, instead of continuous ,of a small signal variable are made, furthermore, the linear approximation is processed according to the different types of converters. Finally the computer calculation data is compared with the experiment results to confirm the model to be correct.
