D200 Class-D Power Amplifier for DIY Audio
Power Amplifier D200 is quite good and reliable in its performance has a power output of about 200Watt 8Ohm. Power enough qualified to drive 12-inch subwoofer speakers. And also no less interesting, this power amplifier is perfect for you who just started (beginner) assemble class D power amplifier. By composing, the circuit of Op-Amp TL074 as a comparator circuit. audio signal and triangular wave then driven again by the driver transistor BD139 and BD140. And the final will be processed by the IRF9540 and IRF540 MOSFET transistor. Then the signal is still shaped square wave will be filtered by a low pass filter circuit to become a sine wave. An output will be forwarded to drive the speakers.
Below the full schematic of D200 Class-D Amplifier, simple Class-D Amplifier and suitable for a beginner of Class D Amp Fans DIY Audio.

What core did you use on the coil in the output filter? Send me the PCB bills. Thank you in advance! [email protected]
ReplyDeleteThe core i use from the Junk PSU PC. Use 22uH .
DeletePlease i want to make a kind of amp, but using two irfp460
ReplyDeleteyou can use class D900 W ot this site.

ReplyDeleteHello! I'm interested on this project but I see there's no PCB file or PDF, only an image. If you want I can collaborate by tracing the PCB using Sprint Layout 6 with all the benefits that mean.
ReplyDeleteHai dear ,
ReplyDeleteplease send clear image and more information of class d amplifier schematics
