Really glad UA-cam recommended your channel when I searched for "Buck Converters". New subscriber. Well explained, clearly illustrated. I love the simulator too! It's now in my toolbox.
The changes in current can be approximately linear, right? I think an LRC circuit will always produce a logarithmic current curve, it would be more pronounced if for example the duty cycle switching freq. was too slow.
I guess you missed the logic, when mosfet switches off, inertia current in inductor changes its direction and voltage spike happens which evens out by capacitor.

Awesome, thank you!
i'm glad i watched this. super helpful in understand the circuit.
Glad it was helpful!
great video! touching on your eureka moments really helped me!
I'm so glad!
Good prep for understanding everything about buck converters
thank you :)
wow that was really amazing. I hope you stick to the series you start not like other youtubers. that would be really helpful. definitely subbed
I already have several videos scheduled for release, so my plan is do definitely stick to the series :)
What switches the mosfet on and off?
Great question, that would be the regulator IC. There will be a video all about those soon!
how does the switch(mosfet) alternate rapidly, do i need to use an external clock like a 555 timer ic?
the MOSFET is controlled by a device known as a regulator IC. I made a video that talks about them: ua-cam.com/video/B7wOFzCd6LA/v-deo.html

Yes, it is okay to linearly approximate the changes in current.

That was meaningless word salad. How about you comment on something you actually know about!
