What about when people hang random, and maybe large, capacitors on the output. As they certainly will if this is a bench PSU. The output terminals are still within the control loop
Hello Ali, can you pls demonstrate practical circuit instability and how do you catch that unstability on bode plot after circuit design followed by its solution. That will help me to understand what exactly happens in circuit due to poles and zeroes.
Wow Bode plots poles & zeros takes me back. Of course there's no real need for formulas and maths because the circuit under development is an Analog Computer in itself
Good explanation. I have a question, what is the disadvantage of just making the circuit "slower" with a bigger capacitor? Obviously this causes the circuit not be able to immediately correct the output. But there are quite some cases where this is not needed at all. So the output voltage can easily be +/-20%
Great tutorial! In reality, how do you physically derive the gain and phase plot? Are there test equipment that does a frequency sweep that will automatically generate the gain and phase plot for you?
Very nice videos, but I have a question that I have been struggling with: how to design for a chip that works with PFM and AM techniques like the AP3918B?, I cant quite understand the operation of it for designing the coupled inductor correctly. Thanks for your time and your videos! I have learned a lot.
Sir, had you said...buck? well a buck does not have a RHPZ and no double pole at cutoff, may you are talking about a boost or flyback?......maybe, other than that stellar video..... as always.
Sir what do u mean by the transfer function of the plant. Is it Vout/d or something else? Can you please explain how the bode100 measure it.. like what ports that serve as the input to the bode plotter?
Отличной урок. Просто, легко и изящно! Спасибо вам!
beautiful demonstration. Thank you!

Really good tool...very helpfull
Thank you for the informative videos. Can you please post a video to how to find the bode plot of the plant. I am using half bridge inverter.
hi Ali
Great lecture thank you.
what is WDS software that you are using, are you selling the software?
Very good ... Super 👌

Impresionante..!!

Great software. Unfortunately out of reach for me being a hobbyist.
I'm still trying to understand what is different between PID vs TYPE II Compensation.

it's the transfer function of your SMPS circuit.
how the hell is biricha the only source of information for digital compensator design
