Accelerating Control Design for Quasi-Resonant Mode Boost Converters through State Machine Modelling Approach

The design of digital controllers for boost converters operating in quasi-resonant mode (QRM) is often hindered by the trade-off between accurately modelling dynamic behavior and efficiently analyzing frequency-domain characteristics. To address this challenge, this paper introduces a novel modelling approach that leverages a state machine to provide a highly accurate and computationally efficient model. By achieving a balance between precision and speed, this method enables faster simulation and design of digital controllers, while maintaining comparable simulation accuracy, thereby enhancing overall design efficiency and effectiveness.
