A new two-input isolated
dc-dc converter based on a distributed multi-transformer structure, which is
suitable for hybrid renewable energy systems is investigated and designed. The
power density of the converter is improved and the circuit structure is
simplified because the power devices are completely shared in the primary side
and the two filter inductors in the bi-directional DC-DC converters and the
isolated transformer in the full-bridge topology are integrated and replaced by
the coupled inductors. With the phase-shifted pulse width-modulation (PWM)
control, the proposed converter can draw power from two different sources and
deliver it to the load individually and simultaneously. The operation principle
of the proposed converter has been analyzed in detail. A prototype converter
with two different DC voltage sources has been simulated and analyzed with
different aspects.
