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.

  27. CIRCUTE DIAGRAM AND PCB DIAGRAM ARE DIFFERENT
    PCB DIAGRAM NOT SHOW 555 TIMER IC BUT THE CIRCUTE DIAGRAM IN 555 IC Why?

  28. amigo ya lo hice y funciona ala perfeccion

  29. This PCB has many errors. Don't try this.

  30. Does somebody build this amp with Original Gerber Files ?

    Mr. Kartino say That is not working PCB, not from me.
    But schematic is correct

    https://www.diyaudio.com/forums/class-d/301218-fullbridge-class-pa-ultra-power-12.html

    I have download long time ago from this website Gerber Files for PCB, but not longer available, now I see this Gerber files should be fake or not tested PCB.

    What is the true before I waste money ?

    ReplyDelete
  31. If someboday want Gerber Files from this amp, before was avaailabale to download I can send

    I dont know working amp or fake Gerber Files, dont have test

    email me: ledshopmalta@gmail.com

  33. Hey carlos excuse my english.

    you do not know whether pcb this amplifier is an functional.

    The last functional pcb model is an this ?
