Yup - it sounds exactly like the boyracer car installations with 2 x 1000W. Lots of bass with 50% distortion.

Indeed, this can't work properly, the chip can't do high frequencies and the output filter is completely wrong. And why would you make a 300 watts digital amplifier for a 5 watt speaker. And no speaker protection. I have a lot of the A-Exprss 1kw digital amplifiers and i have to say it sounds as good as my PA's not bad and tested it for 1500 watts a piece and still no problems. I build 12 from them in a box and 8 1500watt power supplies plus and minus 90 volts. Now i don't need to take all 6 2400 watts amplifiers with me and that's great while those weight 6x35 kg and my own made one only weights 30kg ☺️

@@albertjansen5996 The problem with PWM amplifiers are the very harsh clipping if the input is overdriven. You should not modulate to more than 99%, and that is very hard to control with music input. Besides the output filtering problems ... The circuit shown has one BIG advantage though: It is easy to adjust for a set frequency of 50/60HZ sinevawe using it for a pure sine mains converter, provided the circuit is modified for the required voltage.

Can we use sg3525 instead of using expensive ir2153
@therealjammit3 жыл бұрын
I don't think so. The IR2153 is just a mosfet driver. The analog to digital conversion happen in the op-amp in this circuit. The SG3525 is a PWM controller. You might be able to make something work with the SB3525, but it's definitely not a direct drop in replacement.

@KasyanTV3 жыл бұрын
@@susobhan-5139 At 2153, a conventional converter is made, provides a carrier with a fixed frequency. We modulate the analog signal to this frequency. At the output of such a converter, the signal is far from sinusoidal, the output filter smooths this signal to more or less similar to a sinusoid. Technically, these days the class is far from ideal, in order to compete with the A / AB class, you need to raise the carrier frequency to very high values, and this will cause a number of problems associated with controllers and rather power switches.

I've tried this class d amplifier circuit, it works but there is a hissing noise and the distortion in the bass sound is quite large, so I don't recommend this amplifier I'm from Semarang, Central Java, Indonesia
@rikzakhamami7454 Жыл бұрын
Did you ever try to bump up the supply voltage?, Maybe that distortion in the bass frequency because of the voltage drop across supply voltage
