Abstract :
This paper presents the modeling and design of the digital controller for a phase-shifted full-bridge converter (PSFBC) in the discrete-time domain. The discretized PSFBC model is first derived and then analyzed considering the sampling effect and the system parameters. Based on this model, the digital controller was directly designed in discrete-time domain. The simulation and experimental results are provided to verify the proposed modeling and controller design.
