Class-D sound GaN power devices are power amplification components used in Class-D audio amplifiers that utilise the semiconductor gallium nitride (GaN). In applications requiring audio amplification, GaN power devices are superior than conventional silicon-based devices in a number of ways.
The following are some crucial qualities and advantages of Class-D audio GaN power devices:
Efficiency: GaN power devices have great power conversion efficiency, which makes them perfect for amplifying audio. Because of GaN’s excellent material characteristics, power dissipation is decreased and total efficiency is increased. This minimises energy waste and lowers heat emission by converting a greater portion of the input power into amplified audio output.
High power density is made possible by GaN power devices in Class-D audio amplifiers.GaN has a high thermal conductivity and electron mobility, which enables these devices to manage higher power levels while yet having a small form factor. Smaller, lighter, and more effective audio amplifiers are now possible, which is particularly advantageous for portable or small-space applications.
GaN power devices can operate at the high frequencies needed for Class-D audio amplification thanks to their quick switching properties. Rapid switching between the on and off states enables effective audio signal amplification, producing precise sound reproduction with little distortion.
GaN’s strong thermal conductivity aids in the effective dissipation of heat, improving thermal management in audio amplifiers. This improves thermal stability and heat dissipation, lowering the chance of overheating and guaranteeing consistent performance even under difficult audio amplification circumstances.
High-fidelity audio reproduction is possible with Class-D audio GaN power devices. GaN’s quick switching times and low distortion properties allow for precise audio signal amplification while maintaining the integrity of the original sound source.
As a result, the audio output is of a high calibre with less noise and distortion. It’s important to note that the output stage of Class-D audio amplifiers often employs Class-D audio GaN power semiconductors.
The amplifier circuitry’s input stage and other parts can still make use of silicon-based devices. GaN power devices and other circuit components work together to balance efficiency, power density, and audio performance in Class-D audio amplifiers, making them appropriate for a variety of audio applications, such as high-end audio systems, home theatres, and automotive audio systems.
The Global Class-D audio GaN Power Device Market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
For maritime, automotive, and battery-powered vehicles, GaN Systems has introduced two whole Class-D high-performance GaN FET amplifier boards and two full audio boost converter systems.
According to the business, it now offers a complete solution set that includes turnkey amplifier designs, power supplies, and boost converters. This enables audio systems designers in the auto, home, and professional industries to combine and match designs to maximise performance for their particular applications.
The new designs enable audio design professionals to produce superior audio products more quickly at competitive rates while reducing time to market. They are optimised for sound quality, efficiency (no heatsinks), space, and cost.
For producers of standalone mono, stereo, and multi-channel automotive and maritime amplifiers, the two new high-voltage boost converter reference signs feature a 210-watt continuous/300-watt peak power source and a 300-watt continuous/500-watt peak power source.
