Abstract
This paper presents a nonlinear output capacitor current programming technique applicable for full bridge phase-shift dc-dc converters with zero-voltage-switching. The control method can make the converter system exhibit fast transient response to large-signal disturbances. The concept is based on sensing the output voltage and capacitor current, and then estimating the output voltage to dictate the gate signals for the switch pairs in the full bridge. The principle of operation will be described. Detailed steady-state and dynamic characteristics of the converter will be given. The proposed method has been verified by comparing the experimental results of a 500W, 400V/48V prototype with theoretical predictions. © 2011 IEEE.
