650 Volt GaN: Highest Quality-Highest Performance Drives Market Ramp
2018
After successful qualification under JEDEC requirements as well as Automotive (Q101) requirements [1], [2], along with the establishment of intrinsic lifetimes with associated failure modes [2], high voltage GaN is now ramping in converter/inverter applications. Among the key applications, compact & high efficiency (including Titanium class) Power supplies for uses such as high performance gaming & cryptocurrency mining as well as data center power are leading the way [3]. Automotive uses including onboard chargers (uni/bi-directional), dc-dc converters and pole chargers are being designed in. Finally industrial users have adopted GaN for compact Servo drives and PV inverters [4]. This paper will review the design, performance and manufacturability of high voltage GaN, establishment of the highest level of quality and reliability standards and key features that led to market ramp.
