Bi-directional Digital Power System

Overview

This system, utilizing Renesas high-performance Arm® Cortex®-M33 MCU and 650V GaN FET, achieves 3.6kW bi-directional power conversion through three designs: totem-pole bridgeless power factor correction (PFC) topology to realize bi-directional digital AC/DC power conversion, Dual Active Bridge (DAB) topology to realize digital DC/DC conversion and a 3-phase PFC system to achieve >98.5% efficiency at 10kW output.

System Benefits:

  • For 3.6kW Digital Power Systems:
    • MCU and GaN FET to achieve high-performance bi-directional power conversion
    • Renesas basic digital power software algorithm package for streamlined solution development
  • For 10kW PFC System:
    • Turnkey solution for 10kW applications with user-friendly platform design
    • 3-phase 380/400V RMS input voltage at 50/60Hz
    • 650V, 35mΩ GaN technology for enhanced efficiency and reliability
  • Energy storage
  • Power conversion
  • EV/HEV onboard charger (OBC)
