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.
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
