This high power amplifier has an output power of up to 1500W at 4Ohm impedance, using a class D power amplifier system, where the power amplifier system is very efficient, the efficiency up to more than 90%, much higher than the class AB power amplifier which reaches 50% Efficiency. As I described in my post class-D power amplifier prior to the posting: 200W Class D Amplifier & 900W Class D Amplifier.
Power 1500W Class D requires several components to make the power amplifier and also pay attention to the components available in the market including; IC Comparator using IC TL071, Transistor Level Shifter using 2N5401, IC Logic using CD4049 IC, protection IC using combination of NE555 and LM311, IC Driver using IC IR2110, with 2 pairs Different Power Mosfet, Toroid, Email Wire, Capacitor MKP , Resistor, Diode, Led, Nonpolar Capacitor, Elco, IC Socket, Heatsink, PCB, Male and female socket, Cable. And below the Circuit diagram of its power amp:
The above circuit is almost identical to the series of Power Amp D-Class 3000W Gambit, a significant difference that is in Mosfet Transistors are used, the Power Amplifier is only using 2 IRF MOSFET transistor amplifier, but this power amplifier also has a high-quality performance, Very large power output. To use Mosfet Transistor I suggest you use power MOSFET with IRFP4227 type because this transistor is very good compared to good Mosfet Transistor for Audio (Switching) than like IRFP460 / IRFP460N, IRFP250, IRFP260 etc.
For ease of making 1500W Class D power amplifier, I also share the PCB layout is as follows:
Electronic Circuit is a good site for hobbyist also who would like to try DIY because it shared good circuits. If you have a personalized circuit requirement you may feel free to request it through the comment box or contact me.
