Modeling a contactless power supply using GSSA method

A high order contactless power supply based on a current-fed full-bridge resonant converter is modeled using GSSA (generalized state space averaging) method. After representing the inverting networking and the rectifier with voltage and current controlled sources, both continuous and discrete models are derived to analyze the steady-state and dynamic performance of the system. The results obtained show a good agreement with PSpice simulation of the actual circuit, proving the models developed can be used for fast system simulation and analysis.
