1600W Power Amplifier Class-G PCB Layout

The following is a PCB layout for a G-class power amplifier, previously here is a little explanation about class G power amplifiers, namely Class G classified as an analog amplifier which aims to improve the efficiency of B / AB class amplifiers. In class B / AB, the supply voltage is only one pair which is often denoted as + VCC and –VEE for example + 12V and –12V (or written with +/- 12volt). In class G amplifier, the supply voltage is made multilevel. Especially for applications that require high voltage power, so that the supply voltage is efficient, there are 2 or 3 different pairs. For example, there is a supply voltage of +/- 70 volts, +/- 50 volts and +/- 20 volts. The concept of class G Power Amplifier circuit as shown in figure 1-30. For example, for soft and low sound strings, the active pair is a supply voltage of +/- 20 volts. Then if needed to drive loud sound, the supply voltage can be switched to a maximum supply voltage of +/- 70 volts.

And here is a PCB Layout power amplifier 1600W Class-G Amp, you can also create or print this PCB yourself by downloading the Layout file in the form of a PDF file. End of posting.

This Class G power amplifier can be supplied voltage up to 120VDC Symmetrical and at least 42VDC symmetrical. This power amplifier can produce power up to 1600W RMS on an 8 Ohm Load with a good and maximum power supply voltage to control this amplifier. In addition to the final transistor, it is also very influential, you can use the original Toshiba 2SC5200 / 2SA1943 or NJW0302 / NJW0281G transistors in order to get quality and maximum results.
