Buck-Boost Transformer

Explanation of how Buck-Boost Transformers work.

I’ve watched almost all your videos I’ve been a master electrician for 40 years and a electrical inspector for about 20.
I owned my own electrical company for years. And taught my men both Electrical theory and Code. I can say without a doubt I have never seen anybody have a better grasp on electrical theory and principles along with an understanding of the national electrical code as you. you are doing a great service to the young men and women who are trying to learn the trade.
I want to thank you for being such a great teacher and helping others support themselves in life

I love the eye contact with hand gestures. Truly feels like I'm sitting in the classroom watching your lecture. You don't rush anything. You give time to think and let intuition set in. Like I said before you are a treasure.

I've hooked up a few Buck-Boost transformers over the decades and simply followed instructions resulting in success...Now I understand what I was doing...MUCH obliged.

Just perfect stuff. I taught STEM topics at UC Santa Cruz and because everyone got ratings from students at the end of each course - lecturers like me were compelled to make the content ACCESSIBLE to as broad a range of student preparation as possible. The unpredictability of students' preparation to absorb the material forced lecturers to work hard at clarity.

Your presentation style is EXACTLY what students need. The explanation is paced perfectly - not too slow. Not rushed. The diagrams are perfect. The logic of the different circuit windings is made so clear, it's impossible to fail to understand your explanations.

Nice job! Thank you.

Dave, Dude you are now my favorite transformer teacher. I learned so much from this video, please dont stop.

We in the utility business call a buck/boost transformer a voltage regulator. Awesome how they work to maintain a preset voltage automatically.
Your videos are awesome for basic understandings.

I'm currently taking my fourth year and these videos you've made are so incredibly helpful for me to remember all the things I've forgotten since I was last in school! Thank you!

Excellent description of buck-boost..thanks.

Just stumbled across your videos. They are great, and informative. They have reinforced what I learned in electrical school.

I went to a great VO Tech high school for that taught us so much. Still after over 50 years can remember being told on all three phase loads to use three buck boost transformers instead of two due to better voltage regulation but nobody seems to mention this. Probably 90% of the buck boost transformers that I did install was on 120/208 panel where a machine needed 240 volts. Years ago I called up a great big used transformer & motor shop to see if they could supply me with a 480 to 575 volt buck boost arrangenent. They sold me used small and maybe three times larger transformers to boost the voltage up to 575 volts. It was on a 500 ton injection molding machine with around a 75 HP motor. Found easiest way to splice the thick secondary wires on buck boost transformers is to use a short nipple and mount them right above at least a 4" trough.

Awesome videos. Thorough and to the point. thank you

[nathanrice]

Good clear explanation. I'm glad I ran across this video.

[srisha]

Simply fantastic explanation!!! Thanks a lot Sir.

[michaelcostello]

Excellent lesson. Amazing stuff. Thanks

Thanks! Hooking up a 230 machine to 208. Kinda know what I'm doing but this verified everything in the transformer manual.

Awesome illustration, my brother. Great parallel you drew between that DC circuit and your AC ones.

I just found this channel, and I love it!!!

A buck boost works great for 600 volt motors that more than likely were Canadian imports into the USA, because 347/600 volts is exclusively used in Canada, but is rather uncommon in the US, but 277/480 is not used in Canada. Also some older industrial facilities, say from the 40s and 50s, ran 600 volt ungrounded or corner grounded delta three phase to their large motors.

Dave, you are a very good Instructor!Peter.

I'll never forget now how buck boost transformer works😁
