Resonant dc- dc converter for Datacenter and super computer applications [articol]

Abstract

In this article proposes the parallel operation of converters for load sharing in datacenters. A new control approach is proposed for switch controlled capacitor LLC converter. The output voltage regulation is achieved by the switching frequency control. 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.
