    Good explanation Thanks! Do you not need to null any voltage or current sources in the circuit before calculating output or input impedance?

    Hello. Can you tell me why you didn't include the parasitic resistance of capacitor in the boost converter when you did so for the buck converter previously?

    "Bulk Converter" as the title claims? Apparently not. According to 0:40 it's about "Anaysis" of a BUCK "Conveter". So I guess it's supposed to be ANALYSIS of BUCK CONVERTER. Unless it's about any sister of Buck Conveter, which is perhaps a Bulk Converter.

    If you want to use LT1016 with supply 0-5V, Vin should stay in 1.25-3.50, so if you want Vin till 0 Vcc_negative should be best -1.25V. Great Video. It helps me a lot.

    I am designing a 12V to 5V buck converter with type 2 compensator i am facing a problem that when i changed the source voltage the output voltage also change while in the closed loop buck converter by changing the source voltage and load the output do not change according to load prospective my output is correct and in source my output change Anyone can help?

    @14:45 Transfer Function has the pole-zero mix-up. Zero Results into a +20dB & Pole results into -20dB cancelling out and provide a flat gain due to Rf/R1//R3...Overall excellent analysis....good way to look at transfer functions from circuit point of view...

      The C's impedance is 1/sC or 1/2pifC. when 1/sC=R, a transition point, also called -3dB point in power, since the output is exactly 50% of input voltage. For power, dB=10log(Pout/Pin). For V, I or R, dB=20log(Vout/Vin). So for Vout/Vin, 1/sC=R is -6dB on the vertical scale or 20log(0.5Vin/Vin)=-6dB. Why -20dB, decade in frequency in a factor of 10. If f_pole=1kHz, one decade is 10kHz. Simulate RC circuit in LTSpice with R=10k, C=0.01u, f_pole=1/2piRC=1.591kHz. If you check the dB value at 15.91kHz, you will see the Vout/Vin in dB will be measured at -20dB, hence the output ratio in voltage is falling at a rate of -20dB/dec. At 159.1kHz, the dB value will be at -40dB, because it is 2 decade awa from f_pole. Hope this helps.

    why are we looking at when the impedances of R and C are the same at 5:22? Why is the result -20db down? Why do we fix the values and call it a pole?

    Thank you very much for sharing your knowledge about power electronics! I recently got interested in building a Boost converter, but being a mechanical engineer it's not easy to get deep enough into this topic to not only understand but calculate and build a Boost or Buck converter. I highly appreciate the time you put into this video! PS: In the video you said that you wrote a book about boost converters. What's it's title? Greetings from Germany, Marv
