This is part 3 of my tutorial series about SMPS. In this video I derive the idea of switching converters from the disadvantages of the linear regulator. Based on that idea I explain 2 switching converter topologies:

1.) The Charge Pump (Switched Capacitor Voltage Converter)
2.) The Buck Converter

    You have some really great videos. You do really super work as well. Great Job, You make this easy to learn as well. All I have forgotten over the years from school I have picked right back up very quickly from your video series.

    These videos are awesome. Can you please post the second part of your Ebay electronics tear down and fix videos? I am really new at this hobby and I am addicted to your videos.

    Respect for the creator if this Great Youtube Series. It's quite easy to understand and follow your ideas. Thanks a lot. Btw, sounds like a German accent.

    Excellent, just excellent videos. Very well thought out and executed. As a 25 year technician, I can say, I've re-learned something from your videos. The direct nature of your presentation is outstanding and I'm sure, will help students and guys with foggy minds, such as myself. I love your German accent. Danke!

    Charge pumps are mainly used in transistor driving circuits aren't they?

    You mentioned that lightbulbs can withstand short pwm pulses of higher peak voltage than the rating, but does that apply to power leds as well, as long as the pwm frequency is high enough?

    @13:40 The light in my head turned on when you said that. claps Great way of teaching things.

    I am really enjoying your series of videos. They are accurate and informative. Well done.

    One point to note where you say our eyes are too slow to see kilohertz flicker of the light bulb. I think you will find a light bulb is thermally unable to respond that fast and the flicker is negligible due the the thermal inertia of the filament.

    I am new to electronics and need a power source for my project:
    IN: 250V AC
    OUT: 10-250V DC 0-10 Amps (current limited) independent of voltage

    Would a Buck converter with some current limiting circuit be a good fit?
    I do not jet understand what the LC-Filter is for, wouldn't a Capacitor Parallel to the Output average the voltage as well?

    Thank you for making these videos, they are very helpful!

    Would it be possible to modify an ATX power supply so it puts out more power (amperage) at 12V?
    thanks

    Great video! I'm fairly good at electronics. I build and repair tube amplifiers. These typically use a linear power supply consisting of a transformer, a rectifier, and filtering. I'm gathering the necessary knowledge and information in order to build a SMPS for a tube pre-amp. I'd like to be able to take 120 VAC up to around 300 VDC (200 ma). Any ideas that could steer me in the right direction?

    Thank you very much for your great video series! You seem to be the only person on YouTube who is able to explain SMPS in a way, beginners understand how they work! So thanks again for your efforts!
