Introduction to TRIAC and TRIAC Dimmer - Utmel

WebThen we can see that a thyristor blocks current in both directions of an AC supply in its “OFF” state and can be turned “ON” and made to act like a normal rectifying diode by the application of a positive current to the base of transistor, TR 2 which for a silicon controlled rectifier is called the “Gate” terminal. The operating voltage-current I-V characteristics … Web5 de nov. de 2024 · Connect triac MT1 to your 0V. To switch the triac on, switch the gate to -5V through 470Ω which limits the gate current to 10mA. You can do this with a transistor or even a 74HC logic gate. Connect the load between MT2 and the other terminal of your 24V supply i.e, not the one you just called 0V. Done.
