I would very much like a follow-up video using a microcontroller, H-bridge and two (small) stepper motors and a full explanation of that circuit's operations. Thank you.
Konstantin thank you for this demo on a useful circuit! I tend to like stronger drives (TO220) because I'm amateur and burn components hehe. Well I have made a similar board but not so tidy as yours! TL494 is per datasheet Fixed frequency but pin 6 works for setting 40-200kHz, how is that fixed frequency?
Hello Arve, The Osc Frq of the TL494 is set by Pins5 & 6 (CT,RT), and stays Fix during the whole Operation (except if you put a Pot at Pin 6). Fixed means, that the Frequency cannot be Controlled/Adjusted Dynamically form the Internal Error Amplifiers. The Integrated Error amplifiers of the TL494 can adjust only the Duty Cycle, but NOT the Frequency. There are other Switchmode Controllers that can do both.
@@KonstantinGrigoriadis ah I see, that explains😀 I think I will be experimenting with H bridges and maybe resonant circuits (convenient with the variable freq. ) I will follow you for sure! All the best / Arve
Nice circuit, never hear of that chip before, but it seems a very handy one. Do you have experience with the LR8N3 High Voltage Regulator ? I have them on stock, ordered them a few years back to play with, but not used yet.
Konstantin, I would like to access the design files for this project or know where I may purchase a few of these if I may, please. Great circuit and clean design. Thank you in advance. Steve
@@KonstantinGrigoriadis Thank you… I think the UA-cam chat eliminates personal info (?). Anyway, thank you, I will send to your address. Thank you, for following up! Cheers!

I LOVE the TL494, but I UTTERLY HATE that it does not have push pull outputs. Some of the GREAT things about it is that it is stable & predictable resulting in easy use.
Hi Steven, you can use the TL598 instead that has PushPull outputs and some more feautures, but unfortunately it's not 1:1 pin Cpmpatible. Cheers, Konstantin
@@KonstantinGrigoriadis Yeah, but I cannot get it for pennies like I can but fake TL494's on AliExpress! :) Seriously, it is expensive, way more that other BETTER chips sadly, otherwise I would have hundreds in stock like I have the TL494. ...not fakes! :)

Noted :-)
Good idea and useful module. I think I'll copy and build a few for fun
TL598 is my favorite one. It has push-pull outputs.
Hello, Yes it's a more modern Version of the TL594 with a Better Output Stage and Internal Circuitry that Prohibits Double Pulse at Either Output.
Please make a video on designing CA6928 bluetooth reciever module pcb

Hi Bjorn, Thankyou. I used the LR8 as a High Voltage Constant Current Source couple Years ago.
Cheers
Well this is amazing. Would you consider uploading the files to PCBway so we can order it straight from there (and you get a commission)?
Thankyou, I will eventually upload it at pcbway or at jlcpcb, Cheers

Hi Steve, Links and open Email Addr are eliminate, yes.... Cheers, Konstantin
Could we get a pdf or a link to the schematics and design.
Please send me an Email to reply you with the Design Files. Cheers, Konstantin
@@KonstantinGrigoriadis much appreciated my friend
