Has anyone used GaN power devices? [Copy link]

 

Gallium nitride (GaN) material has a bandgap width three times that of Si material, a critical breakdown electric field 10 times that of Si, and a saturation drift velocity 2.5 times that of Si. In particular, the GaN-based AlGaN/GaN structure has a higher electron mobility, which enables GaN devices to have low on-resistance and high operating frequency, and can meet the requirements of the next generation of electronic equipment for power devices with higher power, higher frequency, smaller size and harsher high-temperature operation.

It can be seen that the performance of GaN is much better than that of previous power devices, but will GaN be used in general equipment applications? In what scenarios are GaN power devices generally used?

We have an idea to apply gallium nitride to motor drives. We want to find a 100V, 100A gallium nitride. We are still in the selection process. I wonder if any experienced colleagues can recommend a model?

At present, most applications are just gimmicks and have not brought real value

This power is a bit high, I have never come across it before!

I feel its value can be demonstrated in the field of fast charging!

Indeed, we are still in the trial stage, thank you

The brands were summarized at the time, including: TI, Infineon, PI Power Integrations, STMicroelectronics, Transphorm, Panasonic, Navitas, GaN Systems, Innoscience, Nexperia, EPC

I wonder how the OP's selection is going? I look forward to sharing it.

Thanks for sharing. I'm still choosing GAN SYSTEM tubes. They have the GS61008T tube, 100V 90A, and it seems to be still available.

OK, there are not many people using GaN at present, I look forward to sharing my experience of touching the stone :)
