You're welcome 😊

Dear Sir! I followed your channel and saw very detailed videos, full of equations. If possible, I hope you can explain the current reflected from secondary to primary in symmetrical pulse source circuits such as pulse sources. half bridge, when using multiple outputs and in my case the outputs use LC buck filter. thank you!

Could you please suggest a good circuit theory book with challenging questions that can assist me in my first year of studying electrical engineering? I've gained a substantial amount of knowledge about analog electronics through watching your channel and completing a 70-hour course on analog electornics. However, most of my understanding has been based on practical, real-life information(through courses), and I haven't studied from textbooks before. I'm eager to begin my journey in circuit theory. What advice do you have for me?

Sorry, I am not that up to date on current textbooks.

Hi sir, I recently started studying analog circuits and I find concept of "common mode" voltage to be very confusing in differential amplifiers. Some texts write it as common noise which is injected in signal, some texts show common mode voltage as some sort of bias voltage to transistors. And if assumed it to be common noise voltage in signal or even as bias voltage for transistors, then why it is average of input differntial signals? I know this comment is not relevant with this video's topic, but I want to understand this concept. Please help me to understand this. Thanks

Common mode is the voltage or current referred to the ground of the system. For example, the common mode current of a line fed system is the current that circulates from ground to BOTH the phase and neutral line into the systems. In analog circuits, the input common mode voltage is the voltage between the input terminals and ground. In closed loop op amp the voltage between the input terminals is very small so the common mode is between any terminal to ground. In a differential amp, the input common mode voltage is DEFINED as the voltage between the average of the input voltages and ground. You should concentrate not just on the definition of common mode voltage but what it is used for. Once you understand this, the logic of common voltage definition will become clear.

I have some doubts is it possible to connect?

Dear sir I'm designing MISO boost converter. It's difficult thing for me that when going to design compensator to PI controller part of the system. Can you do a lecture how we stable the system using compensator and design method of proper compensator using transfer functions. I need to know how we change the gain margin and phase margin of the converter system using compensator.

Hi Professor, thanks for another great video. I want to raise a question to your video of T-model and L-model of a transformer a year ago (kzread.info/dash/bejne/amaJmrJ7fcuYm5c.html). I have tried those four modeling methods in LTSPICE and seen that the two L-models give different results as other two (transformer coupling and T model). I have double checked and made sure the parameters as the same as yours. Additionally, all models give like twice higher than your results at 7:42. Do you possibly know why?

@@sambenyaakov I mean I used all parameters in slide 7 in kzread.info/dash/bejne/amaJmrJ7fcuYm5c.html (btw, Cr is missing in all circuits here) and cannot reproduce the waveforms in page 12.

I believe the L-model has a wrong equivalent turns ratio. The inductance on the side primary side should be: Lm*1k/(N*N)/(KP1*Kp1) - verified by simulation.

You are correct, there is a problem with the L model the way I have put it. I have not recalculated it. Time permits, I will try your solution.
