Abstract
The topology named as the semi quadrupler rec- tifier (SQAR) is obtained by
replacing the fully active (four switches) bridge on the load side of a DualActive
Br idg eRectifier (DAB) by a semi active (two switches and two diodes) bridge. In addition
to the reduced number of active switches, the topology offers several other advantages
including extended zero- voltage switching (ZVS), and smaller output filter requirement. An
Isolated interleaved boost converter is developed based on proposed SQAR. Voltage
quadrupler rectifier is derived in this paper to serve as the secondary rectification topology,
which helps to extend the converter voltage gain. The output voltage is four times of the
conventional full-bridge voltage rectifier with the same transformer ratio, which benefits to
reduce the turns ratio of the transformer. Also, low voltage-rated diodes with high switching
performance can be applied to improve the efficiency. The operation principle is analyzed
and verified by Matlab Simulation.
