Paultre on Power - Power GaN

Author: By Alix Paultre, Editorial Director, PSD Date: 3/12/2013 In this podcast, we talk to Alex Lidow of Efficient Power Conversion (EPC) about GaN devices and their impact on the power industry. EPC is a leader in enhancement-mode Gallium Nitride based power management devices. EPC was the first to introduce enhancement-mode Gallium-Nitride-on-Silicon (eGaN®) FETs as power MOSFET replacements in applications such as point-of-load converters, Power over Ethernet (PoE), server and computer DC-DC converters, LED lighting, cell phones, RF transmission, solar micro-inverters, and ...

eGaN FETs Increase Efficiency, Power Density in Industrial POL Converters

Designers of point of load (POL) converters used in 24 VDC systems traditionally have had to decide between the high cost of an isolated converter and the low frequency and efficiency of a buck converter. When compared with the 12 V POL converter common in computing systems, the higher voltage of the 24 V POL converter increases FET voltage to at least 40 volts to accommodate switch-node ringing and increases commutation and COSS losses. eGaN FETs, from EPC, offer ultra-low QGD for low commutation losses and low QOSS for lower losses when charging and discharging the output capacitance. In ... Read more

eGaN FET-Silicon Power Shoot-Out Volume 13, Part 1: Impact of Parasitics on Performance

The ability of enhancement mode gallium nitride based power devices, such as the eGaN® FET, to achieve higher efficiencies and higher switching frequencies than possible with silicon MOSFETs has been demonstrated for a variety of applications. With improvements in switching figure of merit provided by eGaN FETs, the packaging and PCB layout parasitics are critical to high performance. This first part of this article will study the effect of parasitic inductance on performance for eGaN FET and MOSFET based point of load (POL) buck converters operating at a switching frequency of 1 MHz, ...
