[9]PUSH PULL AMPLIFIER WITH N CHANNEL MOSFET
HTML-код
- Опубликовано: 22 окт 2024
- A push pull amplifier is an amplifier which has an output stage that can drive a current in either direction through through the load. The output stage of a typical push pull amplifier consists of of two identical BJTs or MOSFETs one sourcing current through the load while the other one sinking the current from the load. Push pull amplifiers are superior over single ended amplifiers (using a single transistor at the output for driving the load) in terms of distortion and performance.
आपने बहुत ही जबरदस्त तरीके से बतलाया है,,,पर ये जानकारी पूरी तरह से इंग्लिश भाषा में होने से इसे मेरे लिए समझना मुश्किल था,तब मैंने मेरी बेटी को पढ़कर समझने के बाद इसे हिन्दी भाषा में ट्रांसलेट कर मुझे समझाने को कहा,,तब ये मुझे समझ में आया,, धन्यवाद जी
Dear sir .. great video ..please keep posting great videos !!
Thank you, I will
2 diodes in series only gives a slight
" voltage threshold delay " to mosfet gates..
The 2 ' pnp ' transistors are for keeping the mosfets in " off " when there is no gate drive..
But it will be floating
@ 0.6/0.7 V because of 1st diode closer to i.c.
better turn off is with one diode connected between base of pnp's & ic outputs with anodes connected to pnp's base/s. also 8k2 to 10k resistor between g- s is usual practice...
of course the best is to avoid any diodes in the mosfet gate circuits..because there is sufficient dead time built inthe chip and can be increased if necessary..

Sir, can you full sg3525 circuit diagram please
where is your problem?
@@hobby_plus sir, how to audio signal in to the ic and duty cycle resister & capasiter ,
SG3525 is a pulse generator IC how can you use this IC in audio?
It would be really great if you could add real circuit with oscillscope...i know that is quite tedious work
No Biswajit that is not tedious work for me, because i enjoy this. I'll try to do this, if you sagest me the topic.
@@hobby_plus Hi sir I have some topic in my mind like
1. Flyback and Forward Converter design (using mostly discrete circuit because using IC is quite easy and it kills the learning scope )
2.Buck converter control design with discrete components
I would lick to make videos on your topic one by one please give me time and keep watching. Thank you.
@@hobby_plus Many Thanks 🙏 Sir
Master hi.i precisely fasten this circuit with tl494 with that gate driver that learn from you .but when attach pnp collector to earth shape of pwm full change .I send you that shape.😢😢2 or 3 time made circuit in output the situation is very bad.in gate pin pwm shape....😂😂😂😂
I will answer you shortly
