Thanks for the explanation. In antilog controller, it might be not possible to add perturbation at different place. However, through the software, we can add a perturbation at some point. Therefore, my question is where should i add perturbation to measure open loop and closed loop response.

For open loop the excitation could be anywhere For closed loop in has to be in series.

what is your suggestion on DIY building of the injection transformer? what requirements I should consider?

DEpending on application. Foe Power electronics, the frequency range should be 100Hz to 1-2MHz, make sure that the magnetization impedance at 100Hz is at least 100Ohm

can we use this same method for measuring the frequency response and evaluating the stability of a linear voltage regulator (linear power supply)?

A great tutorial thanks for your time and efforts.. highly appreciated. A question for inserting the resistance to create the junction for Bode measurements. I couldn't get a clear understanding as to how the Vf=Vout(R2/(R1+R2))+Vac(R1/(R1+R2)) in the case that you said is not good if Rs is after R1. And how does a low impedance serve the purpose.. I mean it's an AC source it doesn't have a polarity and how does low impedance makes it go in like clockwise direction along the loop? Could you please help me elaborate it a bit. Thanks

I get it that when Vout is considered then Vf=Vout((R1+RS)/(RS+R1+R2)) but then when Vac is considered how you get Vf=Vac(R1/R1+R2)?

Hello Professor. Can you please do a video on modeling and implementation of current mode control?
