High-Frequency, GaN Diode-Free Motor Drive Inverter with Pure Sine Wave Output

October 1, 2012
This article presents the first kW-Class, 3-phase GaN-based inverter. Hard-switched at 100-kHz PWM, its heart is a 6-in-1 power module with 600-V GaN power HEMTs, achieving a new efficiency of 98.5%, a more than 2% improvement.
