Small-Signal Modeling of Phase-Shift Full-Bridge Converter with Peak Current Mode Control

The system-level small-signal model of phase-shift full-bridge (PSFB) converter with peak current mode control (PCMC) is established using the time-averaging equivalent circuit method. The rationality of the small-signal model is verified by simulation. The work in this paper provides a guideline to design control system for PSFB with PCMC.
