Modeling and Stability Analysis of Control Loop of Phase-shifted Full-bridge Converter

For a single converter or a parallel system with multiple modules, the modeling and analysis of the control loop is very important. It determines whether the designed main circuit components can work according to the predetermined state. Modeling and stability analysis of the control loop can not only clarify the working state of the uncompensated loop, but also provide the basis for the design of compensator parameters. At the same time, for multi-module parallel system, the stability analysis of single-module circuit is the design basis of the stability analysis of parallel system.
