Buck Converter Basics (for Beginners) 

Really glad RU-vid 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.

Good prep for understanding everything about buck converters

great video! touching on your eureka moments really helped me!

What switches the mosfet on and off?

i'm glad i watched this. super helpful in understand the circuit.

how does the switch(mosfet) alternate rapidly, do i need to use an external clock like a 555 timer ic?

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.

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 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.
