@@EEWave how to protect the H-bridge circuit from back emf? Does NPN used in this circuit, needs to be logic level transistor or normal to get full current?
You pull the base low to turn the PNP on, and make it higher than the collector and emitter to turn it off. And, to put a PNP into active mode, VE must be at a higher voltage than VB, which must be higher than VC. Another opposing characteristic of the NPNs and PNPs is the direction of current flow. This is what Google says? I am a little confused.
Most people don't have those transistors. I have tons of them because they're my go to for general purpose. Push-pull and current mirror might be good topics. If you email me a decent diy constant current circuit I'll send ya some dollars Deb. I've tried a bunch but don't like them. For 3 watt cobs that need around .4a. I'm renovating my workshop and want to build my own lighting as I have about 60 thousand leds haha. I don't want to buy a special led smps because I have been researching them and plan to build a simple one once I get my diy pcb workflow going. The hardest thing I find is picking out a mosfet driver.
Great work Sir! Thank you for explaining the H-bridge as simple as beginners can understand it. Thumb up and I leave an Abo! 👍🏻👌🏻🙏🏻
Brilliant tutorial. Thank you so much!
Great job. I'm a step closer to my goal now
Best wishes. Achieve the goal.
Very well explained. .thank you so much for this video..🙏
Most welcome 😊

I find these transistors very useful. It can handle 1.5 A easily.
Great explained
Is this the theory of RC vehicles/toys how it is moving forth and back?
Yes, you are right. Some toys have this working concept.
Hii bro what is the operating voltage of the dc motor in general
Perfect video 👌🏿
You put which side front not clearlly you make camara good
