| Abstract |
Field programmable gate arrays (FPGA) based
control of synchronous rectification (SR) is addressed herein
and applied to the conventional forward converter. In designing
such an FPGA-based SR control algorithm, the energy fed back
from the secondary side to the primary side of the main
transformer and then to the DC link is considered to enhance
transient load response. At the same time, the required deadtime
zone between switches is properly tuned to get the
maximum efficiency under the condition that this converter
operates at full load. Eventually, the differences in transient
load response between with and without the proposed FPGAbased
SR control technique are demonstrated via some
experimental results. |
