The 600kW three-phase inverter demonstrates system-level power density and efficiency obtained by using six of Wolfspeed’s XM3 half-bridge power modules. With half the weight and volume of a standard 62mm module, the XM3 footprint maximizes power density while minimizing loop inductance for low-loss, high-frequency operation with simple power bussing.

Advanced double-sided cold plate and highly-integrated DC Link capacitor reduce component count and increase power density. The three-phase dual inverter has greater than 4x the power density of comparable Si based designs and greater than 98% efficiency.

Features include:

  • Optimized for Wolfspeed’s all-SiC, low-inductance, conduction-optimized XM3 power module
  • Complete stackup, including modules, cooling, bussing, gate drivers, voltage/current sensors and controller
  • High-frequency, ultra-fast switching operation with ultra-low loss, low parasitic bussing
  • Enables compact, lightweight systems
  • Increased power density
  • High-efficiency operation
  • Reduced thermal requirements
  • Reduced system cost
