Power Amplifier Class-D Fullbridge D2K 2000Watts

By Unknown 50 comments
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.
