A 600W boost converter that isn't Ming He but might be Drok.
DC-DC Boost Voltage Converter 6-60V to 6V-90V 600W Step Up Voltage Stablizer X- ebay.us/bQnFa1 - Věda a technologie
I love the idea of boosting the voltage for long distance power transport, then stepping it down again.
I adviced it many times for small power generators in gardens
Thanks again for the red tape trick! I have a USB charger with a watt meter on my desk here; it was a PITA to read before I strapped some red electrical tape over it. 👍
"I don't want to blow this stuff up..."
Aww man.
"...today."
Theeere we go.
Love making power supplies from these. I have 2 videos with 2 different models, still working great after 3 years!!👍👍👍
What's a Love making power supply?
@@gordanmilne7034 😂
Very enjoyable video and not a Super capacitor in sight, I also guess the shed was a tad cold so not used:-)
I am also wanting to run power over 350 meters. So looking forward to your next video where you demonstrate this.
I'm glad your picking this project back up. I'm interested on how efficient it is whether its good or bad it is till a neat idea.
From the Ming-He Dynasty.
Removing the fans and repositioning them to blow over the heatmsink would make sense. Perhaps they are only supplied that way for protection during shipping. Certainly the cables look long enough to move the fans.
Enjoy your buck/boost vids. Such enthusiasm ;)
I wish you had a scope, want to see the ripple on one of these under load
I thought he's got one, Rigol or something maybe I can't remember 😀
@@ollieb9875 It's a Keysight
@@cattflap1447 ah! Cool 😀
The serial port on that looks interesting, maybe trying plugging in a terminal
Seconded!
guessing could be a programming port? maybe remote settings - like setting voltage from a pc? intriguing!!!
indeed, I'd love to hook up a microcontroller to turn it in to a battery charger.
Julian, great videos! I was wondering if you could advise. I have a MOSFET which needs ~10V to properly open up, and I was wondering if you could recommend a boost converter that would take around 4-5V input and boost this up to 10V. The input is not constant, so the output needs to follow the input quite well. Any ideas? Cheers and keep up the vides :)
cool! I has looking at one of those 40v 50A buck converters on Aliexpress that popped up recently too bad they are not digitally controlled.
I notice the fans aren't on, mine does the same. I hope it turns on when it gets hot
Will it work with inductive load like motor?
The new one was a bit hard to read with the red tape. It might be better with red cellophane, like you get on Xmas lollies - lol -.
I view of the displays is good without tape.
Again you demonstrate to me that you are " The King of Bench Power Supplies "...wait for the "that's not a bench power supply !" from the comments...cheers.
What exactly is the tape you put on the display?
thank you
But would it charge my laptop ?
I have bought a very similar buck/boost converter on banggood for 20€ to power a 54v LED and I was disappointed to see that it really can’t churn out more than 1.1 amp at 50volts. Even with a good (Xbox 360) 200w psu it wouldn’t give me more than 50-55w of power output.
I made a radiant half bridge circuit video that I present this weekend. I hope you will like it. It recycles the inductive spike energy.
How can you call it a transmission line if it only passes DC?
Surely it's just a cable...
Transmission lines transmit energy. They are also cables. They are also AC or DC.
Just because most terrestrial transmission lines are AC does not mean that they are exclusively AC.
@@ahaveland There might be different meanings in different fields...
In high frequency electronics, transmission line theory uses the telegrapher's equation and assumes electromagnetic interaction between conductors which is strictly AC.
Such transmission lines include hollow wave guides, microstrip and coplanar wave guides etc.
In power systems, there are overhead transmission lines (which have no insulation) and overhead cables (which have insulation).
Using power transmission lines and unbalanced loads, it is possible to have a higher output voltage than input voltage. This is not possible with DC.
Maybe the confusion stems from the phrases 'power line' and 'transmission line' being used interchangeably.
I could be wrong but it's 12:47 and I need to work tomorrow.......
@@AdrianTechWizard No confusion in my mind.
See HVDC and UHVDC in wikipedia.
@@ahaveland
I just went to Wikipedia and it agrees with me:
en.m.wikipedia.org/wiki/High-voltage_direct_current
It uses 'DC line' not 'transmission line'.
Transmission line means more than just transmuting energy.
Look up Smith Charts and transmission lines. They are *way* more than just wires.
There are also transmission lines which work with low energy and act as filters or quarter wave transformers.
@@AdrianTechWizard What is amazing is your OCD pedantry.
shame its not a buck boost conveter could use a nice 200W+ one for a diy bench psu
Chinese stuff has gone very expensive now.
These boost converters are falsely advertised! Can never put out 10A! Not even close, only around 3.5A, that's it. a scam.
