900 V GaN-based sine-wave inverters for three-phase industrial applications
GaN devices are gradually getting attention within the industry along with SiC as a potential wide bandgap device. At present, there are almost no high-voltage GaN devices with voltage >650 V, which makes an inverter design difficult for a three-phase ...
