    Want to try PSIM? - hubs.ly/H0f9wCC0
    Why is PSIM preferred for Power Electronics simulation? - hubs.ly/H0f9wFX0
    Why you should use PSIM for device level simulations - hubs.ly/H0f9wDk0

    Is this that Buck Converter which you design earlier in a video. ?

      I'm not sure I understand the question, in the same video the power stage will not change and I typically use the same power stage for similar videos. This same power stage gets a digital control solution and an outer voltage loop in different videos.

    Sir, where is the schematic for the first run you had of the open-loop buck converter 0:31 ?

      It is not built into the library. Please post in our forum and I can place it there. powersimtech.com/support/communities/

    Sr where can I download Smartctrl? It's free or How much I need to pay for it

    What type of current mode control is this (peak, average, ..)? How did you arrive at the value of .783 for the iref?

    • @altairhowto

      this average current mode control. The current ref is based on having a 3.3V output voltage and 2.5W load.

    May I know, where can I download this demobuck converter simulation files?

      I posted the circuit to the forum, you can download from there.

    I do this for a PI controller everything works I try with a type 2 compensator and it doesn't work why? why? why?!!!!!

    • @altairhowto

      there can be several issue, are you changing the carrier waveform to match your simulation? are you implementing the transfer function properly?

      I try to build a simple pi and type 2 compensator for you. Hope this will help you.

      I have answered this in detail in this forum post. powersimtech.com/support/communities/topic/type2-and-pi-compensator-for-buck-converter/#post-18746
