1:28 Full Bridge topology : Minor mistake drawing in the bridge. One side is connected between two mosfets ( gate and source) while bridge the other side is connected to drain only (ground or negative)

Great video and super helpful. As a bidirectional converter, I assume you would change the circuit to a CLLLC converter and replace the diodes with transistor and diode pairs like the current input?
Is that possible to use llc or lc resonant on converter with push pull topology?
The schematic connection of the H-Bridge to the LLC tank is not correct, the return connection must be made to the second pair of switches
THANKS TO FOOLISH ENGINEER FOR EXPLAINING EACH TOPIC IN DETAIL... I HAVE SEEN ALL YOUR VIDEOS MOSTLY ON MOSFETS.. WILL LIKE TO SEE MORE DETAILED VIDEO ON CAN... AWAITING ......

@@FoolishEngineer regarding to the primary coil of the transfomer,supplyed by the circuitry,if for exemple this primary coil has 90 turns, how many turns must be done to the leakage coil and same question for the other coil in parallel? average? thanks to care ;) also,the mosfet used are well PNP et NPN right? and whats the type of capacitor that must be used? polarised ? non polarized ? thanks to care ;)
what type of channel is use is this circuitry shows here???? is that both N channell ? or N and P channel? or both P channel? please?
very good information

Your videos are brilliant, i would like to go through the psu used on game console ps5. It appears to be a PFC stage 90vac to 260vac to create 400vdc then a LLC TO GIVE 12V AT 30AMP.

6:28 , i think you have mislabelled the Heavy & Light load curve.
@MR-hx6ee
8 күн бұрын
not only in 6:28 but even in LLC when he put 100Ohm to 500 Ohm, I think should be oposite, as when we push high current to the load we might have a big jump while in low load lower gain jump of gain in resonance. and why ? bicose in heavy load the capacitance impedance when in resonace could be minimum current is high then we have ecessive massive current that is why that the jump
You full bridge diagram is in correct. I guess you should revise it or post a not correcting it.
Please sir Hindi me explain kr do
This is literal plagiarism of MPS article: "Understanding LLC Operation"

If this is plagiarism, then what all teachers/professors doing in classrooms is also plagiarism. And we will be forced to learn stuff from the very inventors of the inventions.

@@ramayanamsanthosh7326 I agree, but teachers cite the correct source, that is the important part. You should do this especially since you are copying the images and literally reading out the article.
