| Abstract |
In this paper, a novel interleaving control
strategy for dc/dc converters is proposed and applied to a
new isolated dc-dc converter configuration with two
paralleled half-bridge structure at the primary side and a
new rectification method at the secondary side of the
transformers, aiming at to optimize the design of
transformers and reduce the rectifier diodes voltage
stresses. The concept of this new control scheme is to
interleave the gate signals with an angle in two identical
PWM controlled half-bridges. The two half-bridges work
alternatively when the input voltage is high, but in series
when the input voltage is low. The rectifier diode voltage
stresses are reduced distinctly. The operation principle and
key features of the proposed interleaving control scheme
are illustrated and experimentally verified by a 50V/10A
prototype. |
