Thanks for such a video. I love to see some amplifier video like this .it so pleasure to see audio freak like me .
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.
thank you for share with us!
Very good 👏
Please make
Lab power supply for biggener ( High Current one) 🥺🙏⚡
Simple one
very good!! like!!
Thats a lot of mosfets 😍🤩🤯🤯
Where?
@@visionofwellboyofficial i want to ask the same xdd
Mantab mas bro..🤭
I think it is better to apply IR2184 or Si8234.
See you
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
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
Download link isn't working!
layout file cannot be opened
great video make an class d 5.1 or 7.1 chanel amp....
Пора учить английский:)
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?
Надо разносить частоты шим
do you sell this pcb??
kiks great thankyou
Klass 🤙🤙🤙🤙🤙🤙
Another amplifier!?! - Patience!! anyway thanks for the video - PS: you spelled amplifier wrong!! ;-)
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.
Please build 1000watt class AB Transistor driver board. However Thanks a lot for this video.
Thanks. So far we have only a couple of amplifiers for 200 and 300 watts in plans.
👍👍
Can we use sg3525 instead of using expensive ir2153
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.
@@therealjammit no bro lm311 is a comparator ic which is convert analog signal to digital and feed to ir 2153 ocillator pin to enable and disable .Though this concept we can create high frequency spwm signal..
2153 dear? no friend, you are confusing something, this is a cheap and affordable IC
@@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.
@@KasyanTV sir I make a class d amplifier using sg3525a..so that's why I am telling you ..using sg3525 instead of using 2153(using protues software)...by the way have a great day 😃😃

Hi bro
Voltage and current can be amplified, power cannot.
لو سمحت اريد دائرة باور سبلاي للتحكم في 50 فولت 15 امبير
THD+N = 50%?
Not really, but personally we are not class D lovers. This option is for a subwoofer.
@@KasyanTV Exactly! This is perfect for a subwoofer, no high THD needed just move the cone with great force.
@@KasyanTV THD50% can be heard also in low tones.
Shipping cost so high....
300w with only +/- 30v?? Is joke??
it was sayin +-60volt for 300w
Unsubing all channels until the dislike button works. No dislike? No like!
