(0030) Comprehensive Topological and Controllers Review of Isolated Bidirectional DC-DC Converter for Renewable Energy Applications

Rahmi İlker Kayaalp, Tuğçe Demirdelen, Mehmet Tümay


There are lots of bidirectional dc-dc converters (BDCs) in renewable energy applications such as photovoltaic systems, wind energy and electric vehicles. BDC topologies are created with different triggering elements and operated with different control methods for improving the system efficiency. In this paper, firstly operation principle of isolated BDC is expressed and these topological differences are summarized with half bridge or full bridge subtitles. Moreover, lots of control methods are also classified and represented for the available topologies. Consequently, improvement of the converter performance techniques are given and the most convenient topologies and controllers are determined for each renewable energy application by considering efficiency manner.
