600 kW XM3 High Performance Dual Three-Phase Inverter

The 600kW three-phase inverter demonstrates system-level power density and efficiency obtained by using 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.
