Hi, really great video, I wonder why this channel doesn't have more susbsribers. you just earned one. I have a question at 8:16, at T4 how does the current INp build up if both Q1 and Q2 are open?

Thank you so much for the video. My name is Laith from Iraq. I watched all your videos and loved them all. I am excited to watch more new video on your channel. ✌✌ I have a question, is the Active Clamp Forward Converter the same Flyback Converter? Thank you, ✔✔

Thank you for the video. What is the purpose of this converter?

Hi Sir, In which tools you these video

Liked your graphics and explanation, however the active clamp forward converter does need 2×vin rating for Q1, infact more than 2×vin is required as you are going beyond 50% duty cycle

Hello. Is there any literature on the method of calculating elements? It is especially interesting to learn about the calculation of a transformer on square cores or on planar

Great video. Just a minor correction, your body diode of pmos is wrong at 4:37. Otherwise fantastic video!

You speak without some very distracting inflections other EE youtubers use, instead you sound much more natural. I appreciate that, makes it easier to pay attention to the content. Speaking of which, the graphics are good as others said. What software did you use to make this, if you're willing to divulge? EDIT: Also, I see it often stated such as in this video, a hard limit on a power supply type (500W) in this case. Seems that this would almost certainly depend on your component selection and availability, and of course we're ignoring paralleling and synchronizing supplies (obviously out of scope). But it would be interesting to delve into the limiting factors of the actual supply design.

@@FoolishEngineer I didn't understand a little, please clarify in the video you wanted to say that in this topology we need to use a capacitor over 500 volts, or this topology is not advisable to use in power supplies and converter over 500 watts?

Why can't a diode be connected across the primary winding to clamp the voltage at the mosfet to Vin + Vforward?

Hi, which is better, Active Clamp Forward Converter or Double Ended Forward Converter? I think that Double Ended, because it has 2 transistors, which is why it, respectively, can give out more power compared to Active Clamp. Plus, the selection of components from Double Ended is easier. But I found an article on the Internet where it says that Active has such advantages as: "The transformer is magnetized by optimal voltage, i.e. there are no useless losses of the volt-second interval. Accordingly, we have minimal overloads of the components by voltage at the maximum possible transformation coefficient for this topology * The energy stored in the parasitic elements - the scattering inductance and the drain-source capacitance of the power key, not only does not dissipate, but also passes from one element to another, reducing the switching energy * Noise is significantly reduced when switching the power key, since its switching energy is significantly reduced * Due to the reduction of the switching energy of the key, dynamic losses are sharply reduced * The working stroke is limited only by permissible overloads of the elements by voltage * The pulse voltage on the power switch is connected non-linearly with the value of the input voltage, and can reach its minimum value in the middle of the range. · There are no voltage outliers on the power key due to the scattering inductance * It is possible to switch the power key at zero voltage * "Rectangular" voltage shapes make it easy and often without additional components to control synchronous keys on the secondary side " Which leads me to think that just because of this, Active Clamp will be much better than Double Ended, even though someone told me that this is a lie and that if I want normal demagnetization, I need to assemble a full bridge or a half bridge. What do you think about this in general?

Well. You observation is quite right. But selecting a topology is more of a designers choice. there are pros & cons based on your requirement & power you can select the converter.

hi, is Active Clamp working with a mosfet and a Schottky diode the same as with a mosfet and a capacitor?

Dear Sir, The same circuit, but we found the Q1 VDS still keep 2 times of Vin, seems there is some extra voltage added on the X'FMR. Would you please hit me whether any possible mistake will cause the boost Q1 VDS issue. Thank you. Paul Tseng

@@FoolishEngineer Yes sir, the Q1 is 60V, measured voltage on Vds is 30V, within application condition. But we found the Q1 will damage by linear mode operating, with big burn mark under the wire bonding of the source. We had use evb from adi (LT1952-1)to check the wave form, it's keep in 12V. That's what we found. Thank you. Paul
