Renesas presents a comprehensive Grid‑to‑Core power architecture for AI datacenters, combining an AC‑DC Vienna Rectifier with an 800V HVDC bus, high‑efficiency 800V→48V/12V DCX LLC conversion stages. Further regulation from 48V to 12V is achieved through advanced Hybrid Switched‑Capacitor or Multiphase Buck converters leveraging Silicon MOSFETs or Low‑Voltage GaN for maximum efficiency and power density. Renesas’ Digital Multiphase Controller and SPS technology deliver world‑class transient response for 12V‑to‑core regulation in AI processors. In the energy sector, Renesas debuts a 500W single‑stage DAB Microinverter, enabled by the new 650V Bi‑Directional GaN device in TOLT package, achieving exceptional efficiency and compactness.
