Power Amplifier Class-D Fullbridge D2K 2000Watts

This is high power amplifier circuit with Class-D system fullbridge which has a power output up to 2000W RMS with the voltage about 90VDC Symmetrical Power Supply (Recomended using Switching Mode Power Supply). Audio Class D amplifier is basically a switching-amplifier or Pulse Width Modulation-Amplifier. A class D audio amplifier has 90% efficiency when the speaker is loaded. While theoretically the Class D audio amplifier has an ideal efficiency of 100%. This Class-D Fullbridge Power Amplifier schematic is originally designed by Mr.Kartino Surodipo. Below the schematic circuit design and PCB Layout Power Amplifier, if you want the PDF file you can download at the links on attachment.

Can you tell who is make the clas d amp design?

you can see at the link Mr.Kartino Surodipo facebook. He is creator and design it. If you want to get more info u can tell with him.

already tested ?

yes its tested and works properly for class d amplifier.

Yes! Class D audio amplifier has 90% efficiency when the speaker is loaded.

hi is it possible to write the parts we need to make this amp
its hard to find it one by one from the pdf you uploaded.
thank you.

just write or post it like the other project as a list (parts will need)

Okay sir i will contact my friend as post writer to update the part list, thanks for your suggestion.
Hope you enjoy in my site!

Help me. What is plugged into the bias connector?
