Modeling and Control of a Dual-Input Isolated Full-Bridge Boost Converter
In this paper, a steady-state model, a large-signal (LS) model and an ac small-signal (SS) model for a recently proposed dual-input transformer-isolated boost converter are derived respectively by the switching flow-graph (SFG) nonlinear modeling technique. Based upon the converter’s model, the controllers are then designed regarding to power stage parameters and system dynamic requirements.
The entire system energy management has been designed as well with the consideration on static and dynamic characteristics of the two different input energy sources. A prototype has been fabricated and tested. The measured experimental results match the simulation results fairly well on both input source dynamic and step load transient responses.
