Next-Generation GaN Isolators for High Frequency, High Efficiency .

Jan 12, 2017 . Half- and full-bridge circuits are the foundations for most power converters / inverters. One critical factor is the ability to control the high-side switch(es) from a ground-referenced controller, i.e. to cross an isolation gap and 'level-shift' the control signal. As converters have been optimized for efficiency, size.
