Studies of Interleaved DC-DC Boost Converters with Coupled Inductors

摘要

Interleaved power converters can be very beneficial for high performance electrical equipment applications. Reductions in size and electromagnetic emission along with an increase in efficiency, transient response, and reliability are among the many advantages to using such converters. Studies of interleaved DC-DC boost converters, which were performed by members of the Power, Energy, and Thermal Division of the Air Force Research Laboratory's (AFRL) Propulsion Directorate, included theoretical derivations and simulations, and experimental demonstrations. The experimental results showed that interleaved designs can provide significant benefit when utilized for high temperature and high power applications. In addition to the electrical performance benefits, it was also demonstrated that coupled inductor interleaved boost converters can be smaller and lighter compared to conventional converter topologies. These study results have been organized and published as several technical papers during the course of this project. In this technical report, the cumulative interleaved coupled inductor DC-DC converter studies are summarized.
