{718} TL494 As Push Pull Driver for Half Bridge, Full Bridge Operation

[@W1RMD]

Thanks! I love your explanations. Current limiting power supplies are a must for checking experimental circuits. SO many components have been saved by SLOWLY "sneaking up" on the full voltage levels. I remember how you said in previous videos the importance of deadtime control and the necessary time required to turn off one transistor BEFORE you turn on the other or transistors will short. Also the importance of checking the transistors that drive the mosfets or output transistors . Best regards!

[@HaseebElectronics]

best regards and special thanks for your valuable encouraging comment yes in smps, there are too may critical and vital parameters, which must be kept in mind while dealing with these circuits

[@jefflyphillippe210]

Merci pour votre temps, et je vous félicite énormément car j'apprends beaucoup de vous. Vos vidéos sont de très bonne qualiter.

PWM only work with frequency above 300hz does not work at 50 or 60hz.

[@doost6233]

The way you described in a mosfet half bridge or full bridge will burn and destroy all the MOSFETs!

[@HaseebElectronics]

no dear friend I explained the bipolar oscillator for these topologies we need to interface the signal properly to next stages as per configuration of next power stage either MOSFET, bjt, igbt etc. either we are injecting directly, or through optocoupler, or through transformer whatsoever but the TL494 switcher will remain same

[@hichamtassi1753]

Very nice video, it reminds me dealing with the old LM723 and its error amplifiers for current limiting function.

[@jboy4real]

I love the way you teach thank for the teaching Please I want you to do a complete video on half bridge convert, full bridge convert and push pull convert with complete details explanation and and all the necessary calculation.

[@HaseebElectronics]

sure i will try my best to do it. but it may take time

[@ministeriomundialliberando8403]

Thank you. Besides, we should think, I mean, if I damage two or three parts, I'll stop and try to find the reason before to continue testing.

[@HaseebElectronics]

you are right. we must see the reasons for the destruction of the components in case if we ave something wrong

[@ministeriomundialliberando8403]

In my case, I reuse parts taken from scratchs but before to use it definitely in a not known project, I first buy some similar cheap parts son in case of destruction, the cheap one is damaged and once the project is tested good, then I use the best part I have.

[@DevUbaidullah]

Thanks You sir, I see your all video. Your video really help me

Very interesting subject on request brother from long time about MOSFETs or IGBTs gate resistor calculation If you get a time make it thank you for always very informative videos Best regards from Philippines 🇵🇭

[@Dc_tech386]

Sir I must apologize to on the push pull the circuit was put together properly the issue was the mosfet I got from the electrician system was all bad when I test the mosfet today I buy the mosfet all was fake fet I did use igbt as switching and the circuit work smoothly the only thing am having issues with is the feedback controller which pin do I con the 15 dc voltage to so the ac voltage stay the same on load am dropping voltage from 240 to 160 so you did explain the right diagram the mosfet was the issues i just need a reply on the feedback voltage connection which pin to add the feedback voltage to pin 3 or 15

[@susantaatha6468]

Beautiful information

[@HaseebElectronics]

best regards and special thanks

[@k.subashjeyanth90]

whether it can be used for interleaved topology

[@johnbarry8185]

Can you design something, choose parts(and tell WHY you chose each part), and build some things(small) in your videos? I cannot speak for others, but the biggest problem that I have, is I don't know WHICH transistor, capacitor, etc., for a project.

[@hiralifestyle]

nice lk

I have a power to control the current of the laser bar of the hair removal device, which works with an analog voltage of 0 to 4.7 volts and a pulse with a range of five volts. It has been having a problem for a few days, and only when it is connected to the 230 V , it only creates 24V of output by first trigger pulse once, and then it does not work until I disconnect and reconnect the 230V input voltage again.

[@hamidh9847]

I check that have dual channel current mode controler pwm ic problems , but producer remove part no. Of IC

[@abidreallife786]

good ji

Thanks Hasseb,would u mind to design a 12v dc to 220v ac inverter as pure sine wave output by using Driver Board EGS002 EG8010 + IR2110 Driver Module

[@mmohaibkht9785]

Aoa sir apka watsap no show hi ni hota ,atx supply me main transformer ko drive ke le transistor ki base ko kitne ohm ki resistance lgi hoti he mere pas diagram ni

[@lifeofapillion8006]

please make a video on Resonant Converter🙏

[@makemollymakemolly1512]

I have facing a problem TL494 ic measuring Oscillation frequency, use push pull drive, I have needed frequency 65khz but it is not increasing 50khz. RT, CT not proper calculation.I have needed 130000hz to single ended operation.Please help me RT, CT calculation measuring properly.
