Resonant converter for data center and super computer applications

Abstract

In this article proposes the load sharing performance of converters in supercomputers. A new control method is proposed for dc to dc switch controlled capacitor (SCC)-LLC converter. The switching frequency is utilized for controlling the regulation of output voltage. It can give the good frequency variation range and peak gain range compared to conventional converters. To attain load sharing the half wave switch controlled capacitor (SCC) is used to control the resonant frequency of each LLC stage. The simulation results are compared with experimental results. A 600w prototype model is developed to prove the feasibility.
