Using SMPS Instead of DC to DC Buck Converter 

This is great idea. Thanks a bunch mate. Tested a number of smps powersupplies and it worked like charm, just make sure the dc voltage is above 41vdc. But if you have a higher vdc the better especially if you'll be having a high load on the smps. This allows the smps to have some spare dutycycle for voltage sag correction.(since at say 41v it most probably running at 100% duty)

life saver man, i have a 70v escoiter and the buck converters are expensive, this saved the day. i even dit some testing with a phone charger, with voltage at input over 50v was able to charge the phone with 2A, and kept 5.2v steady, under 42v at input it worked but dropped about 1.45A at output and 3.8 - 4v. Thanks mate

I just soft-wired my 36v solar panel to a 120v to 12v charger and checked both outputs. 34.7v at the solar panel and 12v at the output of the 12v adapter. Be sure to check the plug for 120v that both tangs are the same size. This indicates that this idea works. If the tangs of the plug are different sizes, then the adapter won't work for output. I checked. Thank you for the idea 💡!

Oh my god. You save me money for dc-dc inverter. Thank you so much

WOW. VERY interesting observation. I will keep this in mind. Makes perfect sense.

Thank You, this will be very handy

Wow 😮 thanks ... very very nice 💪💪👌

Interesting. Thanks!

fantastic great idea.. so simple

You are the best bro.thanks

That's a clever trick.

Well informed

Excellent hint!

Very nice and important experiment.

Thanks 👍

This is super cool. Very non-intuitive, but makes perfect sense when you think about it. Was able to power my wifi and router from my e-bike battery using this trick, when my electrics was being rewired in my house. Awesome.

Respect !
