Customer:
I need help with a DC motor driver for reversing direction. I’m interested in which transistors can be used here. I tried BC337 and BC327 but it didn’t work well. See: http://www.circuitsgallery.com/2012/06/h-bridge-motor-driver-theory-practical.html

Moze li neka pomoc oko ovog drajvera za DC motora za okretanje smera, interesuje me koji tranzistori mogu da se ugrade ovde , ja sam stavljao bc 337 i BC327 i nije nesto htelo da radi…

Soldered Support:
The H-bridge principle is correct. The transistors you mentioned are NPN and PNP which is also good. Based on everything, it should work. I recommend you check your connections and power supply.
It’s easier to build this circuit with MOSFETs: Soldered: Open-Source Electronics, Boards, Sensors & Modules – Soldered Electronics
You’ll need N and P channel: https://electronics.stackexchange.com/questions/306687/h-bridge-mosfet-voltage-drop
There’s also a ready-made solution: Soldered: Open-Source Electronics, Boards, Sensors & Modules – Soldered Electronics

princip H-bridge-a je točan. Tranzistori koje ste poslali vidim da su NPN i PNP što je također dobro(nisam gledao specifikacije u detalje). Prema svemu, trebalo bi raditi. Preporučam da provjerite sve kako ste spojili te izvor napajanja.
Isti krug nešto je lakše napraviti s MOSFETima: Soldered: Open-Source Electronics, Boards, Sensors & Modules – Soldered Electronics
trebat ćete N i P kanalne; https://electronics.stackexchange.com/questions/306687/h-bridge-mosfet-voltage-drop

Customer:
What power level can I use this H-bridge at with 6V and 12V?
Original message (Serbian)
Hvala vam :D, do koje snage smem da upotrebim ovaj H-bridge sa naponom 6V i 12V?
Soldered Support:
If you have a custom solution with transistors, it depends on the transistor specifications. If you use the H-bridge module, the maximum power is 25W. At 6V that’s slightly more than 4A, and at 12V slightly more than 2A.

Ako imate custom rješenje(s tranzistorima), ovisi o snazi tranzistora.
Ako koristite naš modul za H-bridge, max. snaga je 25W. Za 6V je to nešto više od 4A, a za 12V nešto više od 2A.
