Abstract

This paper presents a comparison of two magnetic component topologies for use in high-power high-current dc-dc boost converters. A 97.2 kW three-phase dc-dc converter prototype is considered as the baseline design. The split-winding integrated magnetic (CCTT IM) and two-phase discrete inductor (2L) topologies are then designed to have the same worst-case phase-current ripple condition for a 72 kW prototype. The magnetic components are optimized for varying number of turns in order to achieve the minimum boxed volume. Magnetic and semiconductor power loss are investigated. High-power experimental results are presented for the baseline 3L (97.2 kW) and CCTT IM (72 kW) converters. 3.8 kW experimental results are presented which compares and validates the 2L and CCTT IM concepts under like-for-like operating conditions.
