Default Class D İr2153

I found such a scheme. I did not simulate. Do you work with Irfb4227 and 2x75volt if I draw pcb?

I am not familiar with IRFB2247 and cannot find any data on it.
The IR21531 is an excellent driver with built in self oscillating pre driver. It will work the high side up to 450Volts.

The IR21531 will work as it is, up to +- 90Volts. I have no idea what the IRFB2247 is.

?ndir ampli rar


Yes, Andrewlebon. I traveled a lot in class at Irs900 but it worked before. But I did not love him. I need a 2000-3000w scheme that really works. But he must be able to land at 30Hz. When we look at this chart, the Lm311 is working with 2x10V. I guess the duty cycle signal range can be lowered so that I hear the need to make it wider. So I'll do to meet the amplifier 5000w.

Note : In the raster file you have assembled the pcb drawing for you

I think this is a full bridge. Can you share all these detailed files with me? Lay6 or pdf.
