How To GaN: Paralleling High Speed eGaN FETS for High Current Applications

This column evaluated the ability to parallel eGaN® FETs for higher output current applications by addressing the challenges facing paralleling high speed, low parasitic devices, and demonstrated an improved paralleling technique. For experimental verification of this design method, four parallel half bridges in an optimized layout were operated as a 48 V to 12 V, 480 W, 300 kHz, 40 A buck converter, and achieved efficiencies above 96.5%, from 35% to 100% load. The design method achieved superior electrical and thermal performance compared to conventional paralleling methods and demonstrated that high speed GaN devices can be effectively paralleled for higher current operation.

Yole: Power To Dominate GaN-On-Silicon Market

Yole Développement is releasing, this week, the "GaN-on-Si Substrate Technology and Market for LED and Power Electronics" report. Analysts believe that GaN-on-silicon technology will be widely adopted by power electronics applications. The power electronics market addresses applications such as AC to DC or DC to AC conversion, which is always associated with substantial energy losses that increase with higher power and operating frequencies. Incumbent silicon based technology is reaching its limit and it is difficult to meet higher requirements.

How To GaN: eGaN® FETS in High Performance Class-D Audio Amplifiers

The quality of sound reproduced by an audio amplifier, measured by critical performance parameters such as THD (Total Harmonic Distortion), damping factor (DF), and T-IMD (Inter-modulation Distortion), is influenced by the characteristics of the switching transistors used. Class-D audio amplifiers typically use power MOSFETs, however, lower conduction losses, faster switching speed, and zero reverse recovery losses provided by enhancement-mode GaN (eGaN) FETs enable a significant increase in the sonic quality, and higher efficiency that can eliminate heatsinks. The result is a system with better sound quality in a smaller form factor that can be built at a lower cost.
