Yes, actually I don't know why I put 10Ohm, as a pull up you Need a Least 1k, 100Ohm Is a strong pull up, probably I forgot a K? Anyway, this was From 1 year ago, now I don't do this mistakes anymore. Sorry for that!

You are right. In fact, in the last video of RDC flyback, i added the leakage inductance of the transformer

@@Gabriele1979 Ciao, si, questo è un canale di Ltspice, canali redpill già ci sono come quello di Cris alla fine. Mi piace molto condividere le mie scoperte in ambito elettronico

@@manoA98A Ltspice? Spesso usi termini inglesi che non capisco, al di là del contesto, comunque, per principio, non li uso. Ho alcune obiezioni (minori), a quello che vi siete detti, come quando Cris ti ha consigliato l'asiatica con la frase: usiamo le armi che abbiamo.. ma che caz... vuol dire? Se ti piace, bene, se non ti piace, meglio da solo, fidati. Secondo, la tua soglia di 28 anni è troppo breve, se hai 26 anni. Non voglio gufare, ma per esperienza mia, e di decine di amici e conoscenti, è praticamente impossibile 'svoltare', a meno di accontentarsi brutalmente. Non è scarsa fiducia in te personalmente, ma in generale, se uno non ha una ragazza per anni, difficilmente l'avrà l'anno successivo, è semplice statistica. Forse sarebbe il caso di alzare quella soglia, a meno che tu non voglia espatriare a prescindere

Beh, se vuoi parlarne, fammi sapere, ciao

@@Albiz_96 Ciao! Grazie mille. Sono un ingegnere elettronico triennale e meccatronico magistrale, specializzato in Power Electronics, e ora lavoro come progettista hardware di potenza DCDC

@@tusharrao12 For the Gan, write EPC in the F2 menu. For the SiC, you have to import the model

@@manoA98A thanks

During the Turn On time, in which M1 and M4 are On the current will flow in the positive verse, from left to right in the tank llc. Then the current goes in the secondary side and will follow the same path of the diode (so the first mosfet on the top left will be on). Imagine to replace the passive diodes with the active mosfets. During Ton, M1 and M4 are on on the primary, and the other two mosfet are active on the secondary (Top left and bottom right) like the diode were active passively. I explained this in the video before designign the synch rectifier

@@manoA98A thank you sir. If both side MOSFETs are switched at same time , without any phase shift, whether power will flow? If power flows ,since both are bidirectional switch, power will flow from HV to LV or LV to HV? Kindly clarify my doubt sir.

@@rajeshsethuraman1383 If you ever design this converter in practice, there will actually be a time delay lag between the first bridge and the secondary one. It's not 100% simultaneuous. Plus, when dealing with HV and probably SiC device, there will be additional loss to the discharge of the Cds at each switching cycle which has to be taken in to account. Driver design and auxiliar power supply for the driver are not shown in this video. In real life you will need flyback or push pull to generate 15/20V for the power supply or your drivers, both used for the first and the second bridge

@@manoA98A thank you very much sir

Woh, really? They are Just Spice files lol

No, there are 2 DLL files in that one directory that also contains .CPP files which download just fine. When I choose either one or several files for my download in the ZIP file package, it even tells me that those 2 files could not be downloaded. Weird I know but probably not that weird for Google and Google Drive. Gmail also has limitations on what kinds of files are attached to an email. Great stuff you have there though ! I am happy with what you have done with LTspice. I have only started to use Qspice once or twice so far and it is nice you have some of that as well.

Yes

Very nice, how the signal of the full bridge produce zvs ? Runing phase shifted or how

@@endremurti ZVS in the primary Is reached through the condition explained at the beginning of the video: Min. Dead time and magnetizing inductance which Is able to discharge the CDS of the mosfets

Average model of active clamp forward coverter requires a tons of time and demonstration of maths and paper, in this period i'm quite occupied so I don't know if I will find the time to do that

Link to the video here: ruclips.net/video/plh6mb6SnPg/видео.html&ab_channel=Mano

Hi! 1)Correct 2)Yes I forgot param 3) Yes, unfortunately I messed up the polarity of the transformer , like you said it's the same energy that it is transfered

Hi The point of the bootstrap Is to make the VGs voltage indipendent from the load. The VG voltage charges to 12V+Vdd according to kirkoff Law during the turn on. Because Vs Is at VDD since the MOSFET Is on. So the VGs Is 12V and in fact it's on. That part of the video Is Just to explain how the charging system work, but the real implementation of the bootstrap Is explained later. You normally connect the bootstrap capacitor After the diode and in the source

@@manoA98A Thank you for your feedback But as I understand, your are using Kirchhoff law in a not closed circuit as betwen Gate and MOSFET source there is no continuity

Yes lol, this was one of my first videos and I put the load randomly. Plus, the snubber is also missing

plz reply 🙏 🙏

Certo, ed è giusto che ti dia solo un ramo, perchè tu la caratteristica del comparatore la fai da sinistra verso destra, e tu segui "le freccie" della caratteristica, non ottenendo quindi "il rettangolo" dell'isteresi. Se tu parti dal negativo e vai verso il positivo, allora vai da sinistra verso destra. Se parti dal positivo e vai dal negativo, allora segui le freccie al contrario ma in ogni caso otterrai solo uno dei due rami 1)Se vuoi ottenere entrambi i rami, non devi fare DC sweep, ma mettere un seno in ingresso e nel grafico del plot, fai tasto destro dove c'è scritto time e metti V(in). (Naturalmente devi aver chiamato il nodo (In) altrimenti non funziona: se segui il video passo passo otterrai il bellissimo retttangolo dell'isteresi. 2)Si, è possibile cambiare gli estremi della V(in), perchè ho messo un seno con ampiezza 4V, quindi i valori cambiano tra -4 e 4. Puoi mettere un seno tra -10 e +10 se vuoi ampliare i tuoi estremi

The type 3 compensator Is used for voltage mode buck converters and converters which their configuration are derived from It, like half bridge, push pulls , forwards etc... The flyback Is a buck boost topology derived and It required a type 2 compensator for both current and voltage control

Ero abbastanza sicuro di essermi mutato in quel pezzo ahahah

I can make a video about integrated voltages references. They are mandatory in integrated circuits, they must be stable with the temperature and be realized with the physical proprieties of the device. In that case : the vth threshold voltage of the mosfet, which is constant with the temperature (almost)

@@manoA98A great, looking forward to it. I didn't mean only voltage reference circuits, but other useful circuits as well like current mirrors and more. If there is a good reference for those, that would be great. Appreciate your content.

@@RaedMohsen I probably got what you want. The "useful circuits" that you are looking for, probably, are analogic circuits blocks with npn and pnp. Well, those are mostly used in analog integrated circuits, and in principle, they are 1)Current mirrors/amplifiers 2)Voltage buffers 3)Current Buffers 4)Beta helper/Beta multipliers 5)Amplifier stages B-AB, Output power stage 6)Differential amplifier 7)Voltage and current references 8) Darlington / Skylai pairs If you open an 741 Opamp schematic, you will find all those 8 blocks mentioned. For signal processing and conditioning instead, like sensors signals, you want to use opamp circuits, like adder, subbers, gains, rectifiers, filters and comparators

Just substitute the switch with Nmos, select One of the list and then provide enough gate voltage like 5V

@@manoA98A Should the Gate terminal of NMOS be connected to E and then to BV, or is it sufficient to connect it to DC?

@@user-kh3yw6cu7i If the MOSFET Is High side, you have to provide 5V to the VGS, which Is literally Vg-Vs, a differential voltage. So, you First decide your pulse, then with the gain E you connect both the gate and the source and not the source to gnd, or else the MOSFET won't turn on

@@manoA98A Thank you for your video and your advice <3.

@@manoA98A Sorry for the trouble again. I would like to ask how to adjust the square wave generated by the low-pass filter to align with the sine wave. I have adjusted the delay, inductance, and capacitance, but it seems that there is not much change. Once again, thank you. 🙏
