High Power Class-D Amplifier D4K5

Power Amplifier Class D D4k5 1000W 4500W

This High Power Amplifier circuit is a class D power amplifier, which has a high enough power to generate 1000W of power at 8 Ohm impedance - and also more power up to 2000W at 4 Ohm impedance. This Power Amplifier can generate great power if given enough power supply. For example, you can use 30A transformer with 100V symmetric voltage.  Here is the circuit scheme of High Power Class-D Amplifier D4K5:

  32. I think you all should not wast your funds the circuit does not work the guy is a very bad. I tried to do this circuit because of the efficiency of class d I think I will stick to my class Ab which has minimum parts and very clear sound.

    1. Hahaha please dont judge, this class d amp is works. The power is more high than your class ab.

      Delete
  33. The circuit is a scam it doesn't work. All what they say is class d is efficient but to me most class AB on the Internet is far better than this circuit. Like renowned Nelson pass all his article and amplifier are best and sound great.

    1. what the diode u using? is there oyu using 12V ?
      use 0V 12V

    The coil is 2.5mm thick, wound on an inductor core and measured at 22uH, which generates a lot of heat.

If I measure the voltage on R8 it drops from 2.2v down to about 0.8v, but the voltage one R7 remains at -5.8v. So there is no +5v for the TL071 IC? I have changed R7 and R8 from 6k8 to 10K. Any suggestions on how to get the amplifier working would be appreciated.
