Data center electricity consumption has been increasing rapidly in the last few years as computation moves into cloud computing. In order to reduce the conduction losses in the DC bus, 48 V has been proposed to replace the existing 12 V bus voltage. To adapt the old 12 V infrastructure with the new one a DC-DC converter can provide the interface between the 48 V bus and the regulated 12 V rail. In attempt to define a new benchmark for the 48 V to 12 V conversion, this webinar focuses on two novel Infineon topologies. The first one is the Dual-stage Regulated Hybrid Switched Capacitor (DR-HSC) converter consisting of a combination of the resonant switched capacitor converter and a novel dual phase three-level buck converter, which intrinsically enables flying capacitor balancing throughout inductive energy. The second one is the Regulated Hybrid Switched Capacitor (RHSC) converter which combines Hybrid Switched Capacitor (HSC) and Sigma technologies. Infineon is currently proposing DR-HSC and RHSC, respectively, as regulated and semi-regulated solution for the new OCP 2.0 standard.
