GaN ePower Stage IC-Based Inverter for Battery-Powered Motor Drive Applications

GaN ePower Stage IC-Based Inverter for Battery-Powered Motor Drive Applications

GaN transistors and ICs allow increasing power density in motor drive applications by eliminating electrolytic capacitors in the input filter. The superior switching behavior of GaN helps to remove dead time and obtain un-matched sinusoidal voltage and current waveforms for smoother, silent operation.

GaN eases Silicon out

GaN eases Silicon out

Just like life’s reality, when the aged leaves the center stage for the younger ones, Silicon is taking the bow. The advent and adoption of Gallium Nitride (GaN) have succeeded in gradually easing out the old reliable Silicon. For over four decades, power management efficiency and cost have improved steadily as innovations in power MOSFET structures, technology, and circuit topologies have kept pace with the growing need for electrical power. In the new millennium, however, the rate of improvement has slowed dramatically as the silicon power MOSFET approaches its theoretical bounds. At the same time, the new material, GaN is steadily progressing on its journey toward a theoretical performance boundary that is 6,000 times better than the aging silicon MOSFET and 300 times better than the best GaN products on the market today.

GaN Integrated Power Stage – Redefining Power Conversion

GaN Integrated Power Stage –  Redefining Power Conversion

Beyond just performance and cost improvement, the most significant opportunity for GaN technology to impact the power conversion market comes from its intrinsic ability to integrate multiple devices on the same substrate. GaN technology, as opposed to standard silicon IC technology, allows designers to implement monolithic power systems on a single chip in a more straightforward and cost-effective way.
