What is an H-Bridge?

If you've ever wondered what an H-Bridge is, you've come to the right place. We go over the topology of an H-Bridge, how you use an H-Bridge with a DC motor, and how you can make an H-Bridge with relays or make an H-Bridge with MOSFETs. After discussing how these work, we discuss the different driving states of an H-Bridge and some of the concerns you may run into, such as shoot-through. While we think this animated demonstration of how an H-Bridge works can be extremely helpful, we also recommend checking out the written tutorial on CircuitBread.com at www.circuitbread.com/ee-faq/how-does-an-h-bridge-work

Hi everyone! Someone found an error in the original video so we took it down and are now republishing it with that error corrected. Sorry for the confusion!

You're a true master and I really love your way of speaking and even your voice: I could listen to you for hours! 😁

It would be nice if you make data logger tutorial somewhere in the future. There is practicly not a sningle useful tutorial about that on YT. It would be nice to measure temperature for example and transfer data to PC to make some graphs, temp vs. time etc..

Few queries about H-Bridge: 1. Can it vary duty cycle and frequency? 2. If an H-Bridge is connected to a copper wire of length 15 metres, will the wire see a voltage drop due to impedance? If yes, how to overcome that impedance ? Thanks!

Hey I love the series so much that I subscribed.(I love your Vids) But I have a question. Can the PIC10F200 be programmed in the same language as in the arduino IDE? (Please respond)

@CircuitBread 3 ай бұрын

Arduino uses a propriety C-based language that is very similar but not the exact same. So, while the PIC10F200 can be programmed with a very similar language to the Arduino, it wouldn't be the exact same. There are some projects out there that add support to certain PIC MCUs but I'm not very familiar with them and, as far as I can tell, they don't include anything for the PIC10F200.

i mean, using 4 nmos isnt an error, it requires more external circuitry to drive it in most cases and is probably just less common (it exists) all that and it is still less efficient it s not like pmos is rare or something, dunno why anyone would ever use 4 nmos

True! Perhaps error isn't the correct word but it certainly isn't best practices for the reasons you mention. Either way, we're really trying to keep these as accurate and beneficial as possible so we're being more aggressive about reviews and replacing problems. Things still slip through the gaps sometimes, though.

I actually invented an ultra efficient motor with a multitude of operating modes. AC, pulsating DC and various combinations of the two. An H-Bridge and algorithm run microcontroller would certainly expand upon it's functions.
