Abstract

A power converter supplying kilo-watt-power from its output side is developed in this paper. The composition of its power-stage includes an AC-DC converter and a DC-DC converter. The topology used by the DC-DC converter is the phase-shifted full-bridge with parallel current-doubler rectification converter (PSFB-PCDRC). For the sake of feedback controller design, the small-signal model of PSFB-PCDRC will be set up and employed further to analyze frequency responses. Moreover, the three-terminal switch model is used in this paper, therefore, the transfer function of PSFB-PCDRC is available to be acquired to simulate and analyze the frequency responses. Via practical measurements, the derivation of small-signal model and system compensation parameters can also be approved. The analysis and design procedure will be presented thereafter in the paper. Moreover, the simulations and experimental results are verified that both of which exactly correspond to the anticipated results of the theory, and furthermore, the validity of proposed design approach will also be approved and demonstrated.
