I love the way he built the circuits with the wire for simplicity and also the yellow/green double arrow LED indicator. Genius!
Excellent video!!! I like the way you solder all the components to resemble the schematic. And using the LEDs to illustrate which transistor is switched on is brilliant. I really learned a lot from this video. Thanks for taking the time and effort to share this, it is really appreciated.
nebe01 Thanks! The base principle of my Project is: I am trying to illustrate what I am talking about (even if it is very time consuming) and not to talk about things I am not showing in my videos. I am trying to get better with each new video...
Thank you for taking the time to not only lay this info out, but also for the schematics on your site. Great info. Well explained.
You're welcome!
Thank you very much for making this video. This is by far the most detail video on H bridge that I've even seen.
Great video!
Great video, very detailed. In the Title did you mean "Principle" you are missing the "n".
Thanks!
You read my thoughts correctly. I really enjoy wiping out errors - thanks again.
Would the H-Bridge with 4 N-Channel MOSFETs work if I only used 12V or do I need 12V and 5V?
+Proto G You need a voltage that's above the voltage used to power the load, to make the high side MOSFETS turn on.
Great video and cool accent! Don't change a thing! :)
Thanks!
Improving the video is possible, changing my accent isn't! ;)
Im trying to make a mini RC car using an Attiny85, im going to be using an hbridge for the motor control. The problem that i have is that i only have 3 available pins to use for the motor control since 2 of the available 5 pins are being used by a bluetooth module. My question is if there is anyway to control an hbridge to go backward, forward, left and right, but do using only three input pins. Thank you in advance.
As demonstrated in the video, 2 pins are sufficient to control an H bridge (05:44 Two input clamps).
The schematics are available at the project page (section "simple control"):
www.homofaciens.de/technics-base-circuits-h-bridge_en_navion.htm
How would the dynamic braking change if u we're running a three phase motor? Would all low side or high side mosfets turn on at once, or is there a pattern that happens?
Turning on all high side mosfets at once is the most simple way of braking brushless motors. By adding sensors and so complexity to your circuit you can improve the braking (or recuperating) capabilities.
Amazing !! Thanks for sharing
ahmedadelhosni90 You're welcome!
Спасибо Вам.
Mr. ПоделкинЦ You're welcome!
@1:30 that's not an H bridge, you have two bypass transistor circuits in parallel.
It's an H bridge without a load connected, so in principle you are right.
What kind of transistors are those?
Have a look at my project page:
homofaciens.de/technics-base-circuits-h-bridge_en.htm
Great tutorial, didn't understand the "pulz wife zignal" though.
My videos are published under Creative Commons, thus you are allowed to remix the video with a new audio track, correcting my error(s). That's the principle behind open source and CC.
At what age did you start electronics ? Just curious
When I was 19 during my apprenticeship as physics laboratory assistant.
wow... and Thanks for the reply.
Thanks a lot for the video shared, its very helpful. I have a query, I want to implement the H-bridge that you've shown on your project page, but the motor I have is 24 volts 3A, so what consideration should I have to replace components in your schematic ( www.homofaciens.de/bilder/technik/servos_015.htm ). I've already bought some components.
+erwin escobar The problem is the too high Gate-Source voltage of the power transistors IRFZ34N / IRLZ24N I am using in my design. The maximum is 20V / 16V. You must implement voltage dividers on the gate sides of the power transistors.
For example, would this work? i.imgur.com/2mk6u5k.png
+Proto G
...but this one uses two different voltages (12V and 48V). Is that your drawing? I doubt it will work...
Very good video but the accent is killing me
...you don't have to die!
1.) You can remix the video with your own, beautiful voice: It's creative commons so you are allowed to do so and I am curious what my video would sound like.
2.) Turn off audio and turn on captions.
I feel sorry if my audience dies out because of my German accent...
