IV. CONCLUSION
This paper focuses on the comparison between the LLC
resonant converter and the soft-switched phase shift fullbridge
converter mainly in three parts when they are used as
the front-end Dc/Dc converter of the power supply adapter for
the medium power level applications. LLC resonant converter
definitely shows better performance in conversion efficiency
and power density, no matter in the theoretical analysis or in
the experimental results. But its relatively narrow bandwidth
increases the difficult in dynamic response consideration.
Large output capacitance and Dc bias capacitance are needed
to guarantee the acceptable output voltage drop during the load
shift and the control circuit operation during the burst mode.
