Operating frequency 500Hz-100kHz
Maximum output current: 250mA
Output voltage: DC 5V
How is it possible to set the duty cycle less than 20% in frequencies above 20 kHz?
@@СергейЛабунский-б6ц never operate below 20% ducty cycle....it will not give you good efficiency
Very versatile IC can also produce a second duplicate waveform from the other output 180 degrees out of phase, so suitable for switchmode power supplies or boost converters, the feedback pins used here to regulate the duty cycle directly can with extra circutry be used for voltage and current regulation. And thank you for Beethoven. Classical music is used too little on youtube, especially considering it is royalty free.
Thanks for the feedback - glad you enjoyed it
very good❤❤
Very helpful video and thank you. I want to ask a question. Can we change this circuit with 2 output pwm signal?
yes
Creative video, thanks :)
Thanks for the feedback - glad you enjoyed it
Pls make tht circuit.. Without any pcb or printed circuit board....then it will be lots of easier to make and understand... THANK YOU

How to calculate the frequency without osiloscope ?
Can this be used to power an inverter set up with transformer?
The same controller I have used on the project. Dual drive motor 48 volts on track mobility unit.
Good job 👍
👍
thank you so much for watching
Are you electronics expert?
can i change the turnpot duty cycle using arduino?
how i use it?
thanks
They say a 528hz are a healing frequency how can i build a 528 hz pulse generator
Thank you for your video! I have a favor to ask. Can you please share me your schematic diagram? I am working on a project using tl494

This is astable?
What is the brand of your scope? I would love to have one.
I'll give you a run down on his scope
and i'll tell you from experience what to watch out for
First of all, His scope is likely not just a scope but has a built in Wave Gen.
Secondly it's probably shit to moderate in quality
3. there is no brand, that firstly tells you something
Here is the most likely candidate
www.google.com/search?sxsrf=APwXEdcAS2uyKMWXrD5-J7Ai20h3NtagVA:1687711437207&q=handheld+scope&tbm=shop&sa=X&ved=2ahUKEwiuv8qF797_AhUVqVYBHVX8CfIQ0pQJegQIDBAB&biw=1366&bih=569&dpr=1#spd=15680363424285170920
it's a 2.5" Screen, which is small as fuck
4. so let me give you a run down on this .
Never say... "what's your scope, I want one"
because even though you may find one's that look the same the specs are completely different.
his one is approx $200 AUD now you may find one for $50 but it's likely the specs will be different
RULE 1 - HAND HELD SCOPES AND USB SCOPES (with the exception of Pico Scope) are generally shit
RULE 2 - THEY ARE BUILT TO A BUDGET AND YOU NEED TO UNDERSTAND THIS
RULE 3 - They generally fall in a few categories
CATEGORY "The cheapest and nastiest"
things like FNIRSI (which is the latest knock off) or HANTEK which is ok
things like this , Up to $150 AUD
au.banggood.com/MUSTOOL-MT8208-Intelligent-Graphical-Digital-Oscilloscope-Multimeter-2-in-1-With-2_4-Inches-Color-Screen-1MHz-Bandwidth-2_5Msps-Sampling-Rate-for-DIY-and-Electronic-Test-Upgraded-from-MT8206-p-1707883.html?gmcCountry=AU¤cy=AUD&cur_warehouse=CN&createTmp=1&gltraceid=11280137728&ad_id=609091845756&gad=1&gclid=Cj0KCQjwy9-kBhCHARIsAHpBjHhl-Kz-Uc6rTiUGD3VirETJrEJvj5-_b2JeaaEdaUvNAepT_8MCWScaAjsGEALw_wcB
this is your entry stuff
Ensure that you have at least 100MHz and a min of 2 Channels
THE TRAP WILL BE
THE ANALOG BANDWIDTH
SAMPLING RATE
if you're ona budget you want 1GSa/S maybe even 0.5 if your'e desperate but no less for sampling rate, so ... the one linked here is 2.5MSa/s
you're going to find it really lags
CATEGORY "yeah, ok i guess"
you then step up a little (you should really try to start on this level)
so now you are looking at something like this
www.google.com/search?sxsrf=APwXEdcAS2uyKMWXrD5-J7Ai20h3NtagVA:1687711437207&q=handheld+scope&tbm=shop&sa=X&ved=2ahUKEwiuv8qF797_AhUVqVYBHVX8CfIQ0pQJegQIDBAB&biw=1366&bih=569&dpr=1#spd=14953586329594831701
OR THIS
www.google.com/search?sxsrf=APwXEdcAS2uyKMWXrD5-J7Ai20h3NtagVA:1687711437207&q=handheld+scope&tbm=shop&sa=X&ved=2ahUKEwiuv8qF797_AhUVqVYBHVX8CfIQ0pQJegQIDBAB&biw=1366&bih=569&dpr=1#spd=11480052793385043536
or... i personally have this one
www.google.com/search?sxsrf=APwXEdcAS2uyKMWXrD5-J7Ai20h3NtagVA:1687711437207&q=handheld+scope&tbm=shop&sa=X&ved=2ahUKEwiuv8qF797_AhUVqVYBHVX8CfIQ0pQJegQIDBAB&biw=1366&bih=569&dpr=1#spd=14711980985938428019
it's pretty good, has a wave gen, built in DMM
but now does it need to be handheld ?
why not get something like this
www.google.com/search?sxsrf=APwXEdcAS2uyKMWXrD5-J7Ai20h3NtagVA:1687711437207&q=handheld+scope&tbm=shop&sa=X&ved=2ahUKEwiuv8qF797_AhUVqVYBHVX8CfIQ0pQJegQIDBAB&biw=1366&bih=569&dpr=1#spd=12650969435012252226
it out specs the others anyway
so that's the size of it
you need to watch out for
NUMBER OF CHANNELS
ANALOG BANDWIDTH
IF WAVEGEN, WHAT IS THE MAX FRQUENCY AC AND DC
SAMPLING RATE
AND REMEMBER IF YOU HAVE 2 CHANNELS AND SWITCH THEM BOTH ON
YOUR SAMPLING RATE WILL BE HALF OF WHAT IT IS STATED
Any questions
Seriously though, if your'e going to spend like $400 or more
why not get a RIGOL DS1054Z OR
DS1104Z-S Plus
This is a budget level bench scope
NO IMPORTANT POINT TO UNDERSTAND
on the DS1054Z the min analog front end frequency is 50MHz
BUT YOU CAN UNLOCK THE SOFTWARE UP TO 100MHz
where as if you buy the DS1104Z S Plus, you get it with 100MHz
Plus with logic Analyzer, (although you have to buy the logic probe for another maybe $400)
both these are also 4 channel
another one worth considering is..
DS2000A this is a 2 channel scope but out performs anything above
the Base Model is 70MHz,
YOU CAN UNLOCK THIS TO 300MHz and you'll probably have it for the rest of your life
Over 10 years ago i had to make a choice
DS100E or DS2000A
the 100E was $500 the 2000A was $1100
i put in the effot, NEVER REGRETTED IT
I now own several scopes
i recently bought a MSO5000 series (now i don't expect you to do this)
but if you can afford it go RIGOL DS2000A
lower than that DS1054Z
i don't know why you'd want to go lower than that because when you consider price vs specs the DS1054Z is something you can get for like $400
hope that helps

What can this circuit be used for?
It's amazing I like this video sir I have ferrite fc1330 can you tell me pwm drive circuit please help me
My brother, does this circuit work with a hydrogen cell? Greetings to you from Yemen
no
Nice background music
Thank you
Thank you dear
Can you make us an assembly of a simple frequency generator which generates a square signal of 1Hz - 1Mhz ?. If possible with NE555.
of course you can
NE555 is literally one of the most common used IC's on the planet for beginners.
there are literally thousands of videos on that specific topic
GOOGLE IT
555 TIMER FREQUENCY GENERATION UP TO 1MHZ
I guarantee you'll find plenty to choose from
as if you needed to ask this question
How get rsense vsense isense??????

yes
Bhai sahab aapke circuit ko jab download karne jaate Hain to aadar site per lekar ja raha hai to aap ya to link Sahi tarike se dalo yah video mein hi uska circuit do kyunki download Ho nahin raha hai
In the schematic it been mentioned that you used TL494S , would TL494CN work the same?
yes
We need the Schematic no is easy to get in the link.
