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. 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.
