Analysis of Small Signal Modeling of Buck Boost Converter Based on Switching Flow Diagram Method
This paper describes that Buck Boost converters have advantages such as low output ripple and controllable voltage,and are widely used in new energy vehicle battery power generation and DC microgrids.Establishing a small signal model is beneficial for controlling the main circuit of the circuit system and designing control loops.It analyzes the Buck Boost converter and uses the switch flow diagram method and signal branch model to establish the flow diagram of the converter,thereby deriving a small model of the converter.
