Buck Converter Operation and Voltage Equation

Here, we introduce the buck converter topology and it's two switching operation modes. We derive the relationship between the input voltage, average output voltage, and active switch duty ratio.

Great video. Well explained so easy to follow. And I love Dr. Kim shares this to the public.

The equation is awesome and brilliant, I haven’t seen it in other videos.

Very nice explanation of working of stepdown dc dc converter under ccm in ss. For deriving the duty ratio equations, it would be easier with the plot of voltage across the inductor.

This is awesome! Thanks!!

Thanks Ma'am. 😍
It helped me a lot. ☺️

Very good. Waiting for buck synchronous on next video.

Thanks🙏

dear katkim... try to upload new concept videos... i always lik ur creative ideas

[@jiteshkumar500]

Why we used diode in buck converter?

[@markkraman886]

It provides a discharge path for the inductor which prevents damage on the MOSFET and source.

1st!
