A Novel Method for Parallel Switching Power with Different Capacity
A novel method of parallel switching power with different
capacity in a controllable current sharing method is presented in
this paper. It achieves proportional current sharing and stable
output DC voltage by using controllable current sharing modes
which output assignable feedback signals to the paralleling buck
DC-DC converters. The validity and effectiveness are verified
through comprehensive experiments. Output voltage is at range
of 8.0±0.4V with energy transform efficiency of 80%. Moreover,
controllable current sharing is established in a short time interval
and it automatically recovers after removing the over current
faults.
Keywords: Buck DC-DC converter, Controllable current sharing, Overflow protection
