Would you be willing to open source your work? I'd love to build a controller like this. Thanks for your videos.

I'm surprised that tl494 can properly regulate the output at these high in/out ratios, without any tricks to increase the duty cycle like a tapped inductor. Also a bit of brute forcing took place - high ratios are not kind to components.

The IR2181 in combo with the MMBTA92 is an interesting PUSH-PULL design, although a bit wasteful of the IR2181. Something like a FAN7171 might have been a better choice. The IR2181 is very common, the FAN7171 less so, but often cheaper.

Very cool! With the startup circuit and the mosfet driver this design might be adapted to any regulator, not just the TL494. But why do you need 3 amperes? It seems excessive. As an alternative, i would suggest you again look into high-side buck regulators, which are technically AC/DC regulators, but all AC/DC SMPS use DC inputs in practice (rectified mains AC). For example LinkSwitch-TN by Power Integrations, MP157 by Monolithic Power Systems, or AP3928 by Diodes Inc. They are more common, simpler, and some of them work with low input voltages. But why is your input voltage as low as 32 volt anyway? Regarding SG3525 mentioned, it does not support 200 volt, nor can it drive a high side N-fet, i.e. some kind of mosfet driver is still needed. Anyway, good luck!

If EUC surpass all vehicle then how come it's not popular compare to motorcycles or escooter or ebikes untill now 2024

Thank you brother love the content

Man, this video is such a gem, i startrd some time ago triying to desingn or find a affordable esc for 120v dc opperation around 100 to 200a continuous, but frankly i just have no idea what i am doing electroniks wise i tried to get an 3 phase mosfetdriver to communicate with an arduino and some mosfets for testing blew that 40 eur driver right up and man as a student i just dont have that kinda monney germany is so expensive. I woukd love to get back someday to my projects. And man u kida give me hope Love this video its so great ! Sorry for my bad englisch, its not my primary language

Have a look at SG3525, is should be pin compatible with TL494 and replace both it and IR2181 as it has push-pull outputs that can do 500mA max each. Used a lot of those back when i was young (over 30 years ago) to build 1KW DC-DC converters. 12V DC to +-60V ....

Great video, ❤

❤

what software did you use for simulating the first power supply?

Huge like

Loved the video great would love to see videos about power supply etc

Like a lot of VESC enthusiasts and EV builders with VESC, looking this. More please

absolut *dingdign* badassss

Awesome! Deep dives are appreciated!

Hello! Your video released just in right time, cause i'm design my own version of ESC, but not finally consider on what schematic it could be realized: VESC, ODrive or maybe some other. I am delighted with the work you have done! Good luck completing the project!

This package is the size of a sesame seed and a small mos pulls a big cart. It is strongly recommended to use a top247 package with a huge heat sink to ensure high power and stable operation.

Bro please upload next part I cant find 4 th part on you channel

The power supply part can use UC3842 flyback power supply. It has a simple structure and can be used for isolation. However, it is troublesome to wind the transformer.

Adding isolated gate drive and isolated current acquisition is necessary

i missed something or tl494 dont support half bridge? Adding mosfet would improve performance on these low voltages

Even though you said you didn't do this for a commercial purpose I would strongly suggest getting this out there dude. It's a great design and it fills a great gap. I hope you truly consider this!

power supply video please

What software are you using for designing

Please do a video on Power Stage

Such a nice design, really well thought out and executed.

Awesome project, indeed! I like to use a solid state relay, when the output amp draw is high and a MCU is the controller. A Crydom SSR is easily driven directly from MCU pin, as it only requires 7mA of current to trigger it. SSRs come in a wide variety of Input/Output Voltages and DC/AC Input/Output Combinations. I built a DIY reflow oven with one. Stay away from the Fostek (spelling?) brand, as they are known to be under-designed and their specifications to be overstated. Cheers.

why not use igbts?

Awesome project dude ! I wish i had the knowledge and confidence to do all of that :)

power supply please.

Very awesome project!

looks awesome!

It should be mas production, it should be a reliable, designed to by easy to fix!!!!! with good manual, and I would be happy to buy hundreds of them. There is plenty people who need it So what are you waiting for!!!

please do a video about the power supply

Nice! I used epc2014c in my thesis for a buck converter, its rediculous how small the pads are, soldering by hand it a nightmare. I want to design my own motor controller at some point, but the BOM gets pretty high pretty quick 😂 might get to it after i finish my synchronous buck-boost MPPT solar controller

❤

ThNk you so much

How did you go tubeless? I've went thru two tubes in 700 miles

Please make a detailed build video if you are able! This is an awesome project that I would love to recreate for myself. Thanks for your effort and have fun out there

what is a poly hole??

hello, i've built one too but struggling with setting and vibration. Would you minde sharing your settings ?

@KamiTech where did you get this ebb36 mount. I would really like to put it on my triple-z Vzbot :D

Casting and molding you should learn it

Very nice and thank you for the inspiration.

please make a schematic of your wiring that you show in the video

Fantastic videos thanks very helpful videos.

Awesome!

Do u mind sharing ur Printer cfg? Got the same Setup, so just curios. The Link below the 3z Video is down. :(

Crazy, I have the exact same setup just air cooled. I've built all 3 vzbot printers. I also designed and machined all my own parts. Gantry tube, pulley brackets, print head mount, motor mounts, and even the bed frame. I also use the EBB36 on mine. Definitely cuts down on wires back to the motherboard. I run the Manta M8P V2 on all of them now. Partly because of having dedicated PWM fan ports. But mainly because the pi and main board are in one package to cut down on wiring. Looks good man! Love the yellow. I went with fluro green on my 330,red on my 235, and fluro yellow and blue on my 150. One of these printers is expensive enough by itself but buying 3 of everything is just crazy.
