man this is the best video explaning those 3 converter on youtube

[@FesZElectronics]

I'm happy you liked it!

[@selvamary4404]

On comparing others, yours explanation were easily understandable .

Absolutely brilliant explanations!!! Thanks buddy!

[@frclayton]

Very nice presentation. Good reference to starting a study on these converters.

[@minamichael2401]

Really you have an amazing technique in explanation

[@FesZElectronics]

Thank you! I'm happy you are enjoying my videos!

[@louco2]

At 13:20 did you mean the difference instead of the sum is the output current? Thank you so much for these videos.

[@kymcainday6677]

Can you make a dedicated video about SEPIC converter?

[@ahmadkadahsalim5048]

good explanation man, great Job :-)

[@guguslangit2230]

zeta 09:00 what frequency do you use sir? i try do simulation in proteus but not work for boost

[@FesZElectronics]

I used 50KHz in the simulations but frequency will depend on the components you used. On the other hand to get the converter to boost - output higher than input or buck - output lower than input depends on the duty cycle not switching frequency. Try playing around with the duty cycle - above and below 50%.

@@FesZElectronics thanks sir, it was work in Psim, Next I will build in pcb, 👌

[@SanjaySharma-pw6ww]

👍 video. Pls give me a link of the stimulation software you are using. Thanks for your informative video.

[@FesZElectronics]

It's LTspice - www.analog.com/en/design-center/design-tools-and-calculators/ltspice-simulator.html

Is this possible to use mosfet instead diode in cuk converter? Something similar to 4 switch buck boost

[@FesZElectronics]

It should be possible, but its just difficult to achieve - the driving circuit is difficult to build. Its a similar story to the synchronous boost - it can be done, but it ends up being to complicated and expensive in most cases, so a simple diode is good enough.

[@mateuszczarnecki1079]

@@FesZElectronics simple diode is not enough for my ~25A up to 10V project

[@FesZElectronics]

As long as you have a driver that can supply the out of phase signal (in reference to the initial switch) and dead time, you could either drive a Pmos transistors with a negative signal (negative voltage in reference to GND); or use either P or Nmos with an isolation transformer.

[@selvamary4404]

Pls tell about combined cuk and sepic converter

[@FesZElectronics]

Interesting topic! I was not aware you can make a diferential supply by combining a Cuk and Sepic onto a single switching node. I did however make a diferential supply using a boost and buck boost in one of my old videos.

[@al.musfik]

Thanks 💖 Can you tell me the simulator name ?

[@FesZElectronics]

It's LTspice. That is what I use in all my videos.

[@al.musfik]

@@FesZElectronics Thank You very much 💖 Have you any link of Zeta Converter Simulate File?

[@selvamary4404]

And what software it is

[@FesZElectronics]

I'm using LTspice to show the waveforms and operation; I find it quite easy to use
