Very clear explanation, thank you

Thank you very much again. I've found empirically that we just divide by 6 the value of power disipated without snubber circuit to know the amount of power dissipated using it.

A very interesting explanation.

Nice explanation as usual, I always learnt something new from your videos hence watching repeatedly and each time get something new.

Hai sir, It was awesome explanation and I have four questions. 1.for peak current calculation formula where 3.13 value is come from? 2.is (tf) value is given in datasheet r how we knw DAT (tf)value. 3.last formula for transistor wattage where 6T is came from? 4.In which way the resistor will discharge the charges at transistor "ON Time" These are my question please give sir to these question to complete this topic sir...

Tf is the delay in fall time which is from datasheet and watch once again video to know how does the capacitor discharges during transistor ON time. But I still did not get answers for 1st question and 3rd question. Here I have added another question. 5. In the formula R1 = Ton_min / (3*C1), What is 3? Are 3.13, 6T and 3 assumption? If yes, what is the base for these assumptions? Only Haseeb can answer these questions

Excellent explanation, respect from Romania.

If I understood correctly, in flyback, instead of a doubled input voltage at the time of closing the transistor, there will be a reflected voltage + a self-induction voltage of the dissipation inductance?

Thank you for the fantastic video, it was very informative and well presented and now I understand what a snubber circuit dose and how and where to use one 👍 Do you have videos explaining any types of circuitry other then Smps?

Thank you so much sir your video helped me understand this snubber network concept very easily, the only calculation part whr i stuck was the last formula where you calculated the pd with rcd snubber which came to be 1.38 Watts, i just wanted to know why we multiplied the T by 6 or to be more precise where the number 6 came from in formula.

Hi Haseeb, Are you still checking the comments? If yes, Could you answer the following questions? . Answers to these questions will help so many of your channel followers like me. 1. How did you consider 3.13 in the Ipeak calculation? 2. How did you consider 3 in the R1 calculation? 3. How did you consider 6 while calculating transistor power dissipation after adding snubber circuit? The explanation of the circuit and calculations are awesome

@MrLuo-lq2yv

Reply about the 2, the voltage in capacitor is reduced almost to zero after three times time constant (3RC), because U*e^(-3) and the energy of capacitor in RCD is expected to release over during T_on.

@MrLuo-lq2yv

Reply about the 1, 3.13 should be related to topology of the circuit, only if you can calculate the I_pk and take some margin into account in your applications, the reason about the value, 3.13, can be ignored.

Explendid and clever explanation .Very practical as well . Congratulations !

@@HaseebElectronics ty sir i want to know about smps pls i will keep sharing your vids

Thanks for the explanation. In an atx power supply, I found the mosfet short and diode blown. I guess it's the diode from the snubber circuit. For replacing the diode is there a special requirement like fast recovery, amp rating otherwise they get shorted again? Why did the diode go short in the first place?

Very nice explanation ! How do you select the diode type in this case ? Based on I peek = 0.85 A and diode response time ?

plss sir make a vids about those capacitor on primary ground and secondary ground /hot and cold

Extremely very good explanation about this topic. in fact, the best one I've ever studied. Can I ask your opinion, since I've seen simulations where when using 12 Vdc of power source voltage, they have measured up to 2500Vdc of spikes, can a such low power source produce such a High voltgae spikes in a coli? I'd appreciate your suggestions. Thank you.

@HaseebElectronics

3 жыл бұрын

best regards and special thanks yes if snubber circuit is not used, these spikes might reach at this amplitude due to winding ratio, reverse emf, switching topology, load, leakage, core permeability so the voltage stress spikes may reach at this level

Asalam Aalaikum It has been so long, I was following you silently, be blessed for your initiative you made of teaching us, you are amazing teacher bcz most of every thing I know about flyback converter it is bcz of you, thx for this, but I want to ask you a favor of clarifying fall time (Tf) you said in this tutorial (284) RCD snubber circuit, you said that MOSFET used in that example has 0,3us of fall time(Tf) after I tried to read more than ten datasheet then I realized that there is no MOSFET with fall time of that range, I saw instead delay fall time(Tdf) may probably be in that range. So, I want to ask if you may give us again some other clarification if that 0,3us of that MOSFET was Td or Tdf? Be blessed, thx.

وعليكم السلام ورحمة الله وبركاته the tf (fall time) or tdf turn off delay or td or td(off) or time delay falling edge (tf) have the same the example in that tutorial was just to give the concept we must have to follow the datasheet for exact calculations

assalamalkm. bro will putting snubber resolve ringing issue I am facing in my smps.my uc 3843 destroyed and blew off zener protecting gate....also is putting snubber on output rectifier is it good? and since rectifier diode is heating wasting power is it acceptable to put some clamp to take care of reverse recovery

Hi sir Please can you make video on bridge rectifier smoothing capacitor capacitance value and also smps output capacitor capacitance value calculations

Thanks a Lot ! Hard to find such a nice explanation! I have assembled a full bridge excited by one TL594 IC at 12,5 kHZ .conected to two IR21844 IC for Mosfet drive . RCD is 2,2uf / 15 ohms and fast diode UF4007 .Mosfets are ok but resistors become extremely hot . What is wrong ? Can you help me ?
