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.

Thanks for such a video. I love to see some amplifier video like this .it so pleasure to see audio freak like me .

thank you for share with us!

Please make Lab power supply for biggener ( High Current one) 🥺🙏⚡ Simple one

Very good 👏

Thats a lot of mosfets 😍🤩🤯🤯

very good!! like!!

great video make an class d 5.1 or 7.1 chanel amp....

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

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

kiks great thankyou

Пора учить английский:)

I think it is better to apply IR2184 or Si8234. See you

Another amplifier!?! - Patience!! anyway thanks for the video - PS: you spelled amplifier wrong!! ;-)

Thanks. So far we have only a couple of amplifiers for 200 and 300 watts in plans.

Hello, your class d 300w project is very beautiful and I would like to have one of those, but what a pity the layout file is corrupted and does not open in sprint liout. If you can share a valid file I would be grateful. thanks

Hi bro

Greetings, why is it that when two channels are assembled for stereo version, an interference noise is heard in the background, while in a single channel that annoying noise does not appear?

is it safe if the speaker output is disconnected or not plugged in when the amplifier is on?

I would say have a load connected at all times. The inductive kick from an unloaded inductor can get pretty bad.

We did not notice any problems of this kind. This device is surprisingly reliable, during the tests I incorrectly connected the polarity several times and nothing happened to it.

Can we use sg3525 instead of using expensive ir2153

@therealjammit

2 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.

@@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.
