Better converter efficiency with eGaN FETs
by Alex Lidow and David Reusch, Efficient Power Conversion Corp. Gallium-nitride FET technology has improved markedly in the past five years. Power converters based on GaN FETs are living up to the promise of low power losses at an economical price. Enhancement-mode gallium-nitride (eGaN) FETs can switch at speeds ten times faster than the best […]
DC-DC converter handbook covers GaN transistors
The demand for information is growing at unprecedented rates and society’s insatiable appetite for communication, computing and downloading, is driving this demand. With emerging technologies, such as, cloud computing and the internet of things, not to mention the 300 hours of video being loaded to YouTube every minute, this trend for more and faster access […]
EPC introduces fast, small monolithic gallium nitride power transistor half bridge operating over 2 MHz
EPC announces the EPC2106, an enhancement-mode monolithic GaN transistor half bridge. By integrating two eGaN® power FETs into a single device, interconnect inductances and the interstitial space needed on the PCB are eliminated. This increases both efficiency (especially at higher frequencies) and power density, while reducing assembly costs to the end user’s power conversion system. […]
Power converters with GaN
by Alex Lidow, CEO, Efficient Power Conversion Corp. It can be tricky to analyze power supply designs incorporating GaN power devices. Here are the basics of calculating losses and device currents when using these exotic semiconductors. There is a lot of activity in wide-bandgap semiconductors these days. They have the ability to operate at much […]
