Abstract

Interleaving method for point-of-load (POL) isolated DC DC converter topologies is presented to improve conversion efficiency, thermal management and transient response by utilising current sharing between switches and magnetics and by operating the secondary-side switches at a lower switching frequency than the primary-side switches. Moreover, in the presented interleaving method, both primary and secondary sides of the isolation transformers are connected in parallel, allowing current sharing at both primary and secondary sides, while utilising a simple primary side. Theoretical analysis, simulation and experimental results are presented to verify the proposed topology and control method. It is expected that this topology will be a good competitor for low-voltage high-current POL DC DC converter applications in present and future generation integrated circuits for communication and computer systems.
