How to make a 4k5 class d amplifier circuit.
This circuit works upto 100v 30amp depends upon the components used on board.
This circuit will will produce a great power if a good power supply used, I am using 50-0-50 14amp toroidal transformer in this project near 980 watt.

This is used for personal use. I am not trying to remove branding of any board in any case it was removed, please comment in comment box with link I will add it in description. I do not want any one suffer loss because of my interest/hobby.

All components are used in this project, is purchased from local Market and it’s easy available in local market or from some website, but some times need to find suitable replacement.

In testing video 2 different PCB used both are given below

All Credit goes to :

PCB 1 (Left side in testing video/ coming soon video):

PCB 2 (Right side in testing video/making of class d):

When the speaker output is shorted, the current will increase in the shunt resistor to report to the ic lm311 as the 555 ic provides a signal to the driver ic ir 2110 shutdow to protect the circuit safely and effectively...

Sir, when the current is applied to the drive side of the amp, it turns on. But when the 40 volt dual supply is connected, the drive side of the amp turns off. The drive side turns on when the negative wire of the 40 volt dual supply is disconnected. Sir, can you tell me why this is happening?
