First time at this channel and the prof is amazing. I am a retired high school teacher whose specialty was digital electronics. I always tried to get concepts across to my students using simple language then explaining what the industry terminology is, and using analogies. The students who excelled at math excelled in my programme.
This is great! I've been messing around with electronic circuits on a hobby basis for years, born in 69, I knew stuff !!! and learned stuff too. Not the last lecture for me, love it !
Whoever published this deserves more than appreciation. Thank you so much sir I'm almost to go to the exams exactly on 20s of January and I was so worry about this course
I graduated electrical engineering a few years ago up in Canada. While I don't do any proper electrical engineering anymore, its always interesting to go back and watch these lectures to get a refresher, and to see how it's taught at a great school like MIT
This content is valuable. Thanks to all that made its availability here possible. Also, very clear instruction. These students are fortunate to have a professor that is such a good teacher.
I'm an amateur electronics enthusiast (mostly repair, some design/engineering) and this is amazing. I definitely never went to MIT or warranted the ability to based on my academic performance on high school (lol). Thank you for these. This professor is very good at his job, btw. I'm about to binge all of these videos and then probably repeat them.
Watched out of curiosity and glad I did. I studied electronics in high school 1972-1976. We were still learning vacuum tubes first, then transistors. Integrated circuits of course existed but were not yet part of the curriculum. To this day I still remember Ohm's law, RC filters and the formula for calculating impedance. Hats off to this instructor, very straightforward and knowledgeable.
Thank you, MIT. I am incredibly grateful for the tremendous effort to make high-quality education accessible to people all around the world! 🌍 At the end, I have a small request. I believe it would be fantastic if you could share the video lectures of the 6.011 (signals, systems & inference) class.
This is friggin AWESOME! Thank you, MIT, for being willing to offer this incredible opportunity to those without the means or opportunity to attend your campus!
The best educational institution in the world, and it still uses the old method of education...truly education is based on desire and love of knowledge.
It's not an old method. This is the basis of education and is not going anywhere. It's merely be expanded on. If a virtual 3d classroom is in the future, is that really that much different than in-person 3d?
Praise to the camera operator for perfectly capturing the stage, chalkboard drawings, and making smooth and controlled movements while keeping the professor in focus.
Mỗi lần xem lại video này, mình lại cảm thấy biết ơn vì đã được trải nghiệm một tác phẩm chứa đựng nhiều thông điệp giá trị đến vậy. Bạn đã làm rất tốt trong việc kết nối những cảm xúc và suy nghĩ, giúp người xem không chỉ giải trí mà còn học hỏi được nhiều điều quý giá. Đây thực sự là một video rất đáng để chia sẻ và lan tỏa.

28:41 It's a "linear" regulator because the transistor is operating in it's "linear" region - it's neither fully on or fully off, and it has a linear transfer function from input to output at those conditions. It's the region you want to run in to amplify signals with no distortion, but terrible for doing power conversion
"Collective" homework assignments that reflect 40% of their grade? Take home. "Assessments" that represent 50% of their grade? I would never have thought that getting a good grade at MIT was easier than my community college or university 40 years ago!
I just stumbled on this. I have no aspirations to be an electronic engineer but now understand the basic principles behing 'switch mode' and the wider implications power engineering. I can clearly see why this course will be so useful to many. From what I have seen, the MIT series looks like a remarkable contribution to humanity in general.
Studied this in the 80s. SMPS - switching regulators. Used I consumer electronics-TVs, VCRs, Ham equipment. Now in everything. Very efficient like 80-90%
Just stumbled on this, fantastic, love MIT OCW and this is exactly what I'm self-studying now. Thanks MIT for this, and all the other courses you've made available. Fond memories of Walter Lewin and all his physics lessons :)
It doesn't get better than free lectures by MIT. It's like being there! And having the ability to learn FOR FREE, except from the convenience of whenever you're located

Thank you so much for sharing this! I absolutely love the idea of free education for everybody. I learned quite a bit just within these 45 minutes. This is awesome!
When i did power electronics 30 yrs ago my lecturer told us the exam is 90% at the end of semester and if you show up before that good, but if you don't he doesn't care, your loss !!! And when you showed up for lectures he just straight up read from the textbook !!!! Oh and whenever you knocked on his office door, he was never there !!! Not MIT but a uni just as big !!! WOW things have changed 😀
Dude I’m self-studying power electronics for my current job! This is such a blessing to be able to access high quality educational content for free! Thank you MIT!!! Also, the professor seems to explain this stuff very clearly and insightfully. I’m looking forward to continuing this course!
I've been using the old school OCW power electronics course notes as a reference for years. I'm so excited to see the coursework from the man himself! I've used that material to help with several designs.
Thanks so much MIT, just please pay these instructors adequately. I know that college educators get screwed over a lot, and that a lot of them barely have any job security
Would be cool if the teacher would repeat students questions so that those listening via UA-cam can hear them. It’s just a good practice for teachers in general. Thanks for sharing!
All will be half bridge rectifirr direct current 3 phases ( ripllingdc ) 3 pases internally but echo encrypted ambient ultrasound when transmited. Eliminate resistor
Wow very valuable video playlist for me. because I am an Electronics and Telecommunication Engineering student. I am watching your videos from Sri Lanka. Please share more videos like this with us.
Let's Go!!! To make it small it needs to be efficient. The approach is Pulse with Modulation (PWM). You can down convert energy in a theatrically lossless approach by pulsing power to an output that will average to the desired output power. This works just fine by itself for devices that can used alternating current but would destroy things like a microprocessor that needs consistent current. However, adding an Inductor and Capacitator can limit the output fluctuation to behave like a consistent power supply for a device.
I wish I had instructor like her m for my Electronics classes then micro instructor instructor that stands on shoulders and laugh at your mistakes then helping anyways I am done with my electronics classes I just keep up with my electronics to learn and stay in loop to stay what I have learned in past including my math classes like Algebra and calculus 😊keep my memory working in wireless and IT areas that worked for 25 plus year of my life😊
the internet i a wondeful thing. from complex RF technology, business studies, mathematics, physics, complex power electronics etc from these high quality institutions all for free. thank the creators of the internet.
Not a fan of the dismissive attitued at the Linear Regulator, hope thats a bit. The efficiency of Linear regulators is dependant on the voltage drop. A minimal voltage drop means minimal loss. They're great as a final stage after an SMPS because you can match up the stages so you get a nice clean vout from the regulator and most of the efficiency of the switcher.
This looks like a fun course! ... especially when you aren't getting graded. 😃 I used to work with a satellite power system that was based on the Skylab airlock battery charger. It switched at audio frequencies, using bipolar transistors and only a few integrated circuits. It's amazing to consider how far switched mode power supply design has come since then.
Really like to see you go further with multiple power supplies on the grid ohm's law 102 and why you can only put in about 15% of the actual watts The missing 85% is overcoming the pressure of the line voltage
Being able to pause the video and read the slides is helpful. I can imagine those in the lecture would probably want more time to absorb some of that information.

Let's Go!!! To make it small it needs to be efficient. The approach is Pulse with Modulation (PWM). You can down convert energy in a theatrically lossless approach by pulsing power to an output that will average to the desired output power. This works just fine by itself for devices that can used alternating current but would destroy things like a microprocessor that needs consistent current. However, adding an Inductor and Capacitator can limit the output fluctuation to behave like a consistent power supply for a device.

Not a fan of the dismissive attitued at the Linear Regulator, hope thats a bit. The efficiency of Linear regulators is dependant on the voltage drop. A minimal voltage drop means minimal loss. They're great as a final stage after an SMPS because you can match up the stages so you get a nice clean vout from the regulator and most of the efficiency of the switcher.
Thanks for the lesson.
This looks like a fun course! ... especially when you aren't getting graded. 😃 I used to work with a satellite power system that was based on the Skylab airlock battery charger. It switched at audio frequencies, using bipolar transistors and only a few integrated circuits. It's amazing to consider how far switched mode power supply design has come since then.
