3000 Watt Power Amplifier Class D Mosfet IRFP260 / IRFP4227

3000W CLass D Power Amplifier Circuit

3000W  (PMPO) D3K Class D Power Amplifier Project using IC IR2110, CD4049 (HEF4049/HCF4049), NE555, LM311, and Op-Amp Comparator TL071 as the main stage amplifier, the driver stage using BD140/BD139 or you can use any driver stage power amplifier transistors. The Final Stage Amplifier using 4 x Mosfet Transistor IRFP260 or you can use IRFP250 / IRFP460 / IRFP4227. And do not forget to lose the importance of the LPF Filter.

Simple Class-D LM311 IR2110 Video Assembling and Test: https://www.youtube.com/watch?v=wW0KCoUaXbc&t

This more high power than this D3K see here: Class-D Fullbridge D2K5

The advantages of this high power amplifier are:

  • Strong Bass Boost, not Saggy
  • Secondary comfortable bias voltage (can be AC (transformer) / DC (adapter))
  • Highly Efficient Rail - Stack Layout
  • Oversized Heatsink & Output Coil (not easy saturation)
  • Pulse Resolution Adjust Enable
Below the Circuit Diagram of 3000W Class D Amplifier includes PCB Layout design:

  3. how can we increase more power? Is it possible to add more stages of mosfets or by increasing the power supply to 150 volts in the same circuit?

    ReplyDelete
    Replies
    1. You can increase voltage up to 100V , you cant adding more stages of final mosfet. But you can upgrade with replacing the mosfet with more Vgs Igd higher.

  10. looking at the lay out of your pcb board,how will you put the heat sink for the mosfets and will this circuit require a pre amp and power capacitors or its all with the board once assembly is complete?

    ReplyDelete
  11. for the heatsink, you must plase the mosfet on back of pcb. and put preamp on nput socket

  12. IS THIS PCB LAY OUT ENOUGH FOR THE AMP TO BE COMPLETE ONCE ASSEMBLY IS COMPLETE OR WILL IT REQUIRE THE POWER CAPACITORS?
