How do I drive a TRIAC from a microcontroller (for low voltages)?

WebJul 8, 2010 · Thyristors (triacs and their unidirectional cousins, SCRs) are solid-state devices, whereas relays are electromechanical devices. Triacs can switch both AC and DC, but as XTL said, they will not stop the current flow unless the current between MT1 and MT2 falls below a threshold level, or you forcibly commutate the device off. WebA triac is basically an electronic switch for alternate current. What it does is to close a contact between two terminals when a current is applied to its "Gate". It will continue … birthing snacksWebJun 16, 2024 · The reader can verify that, regardless of the polarity of the output AC voltage, the gate of the SCRs will have a positive voltage due to the current which goes through the TRIAC.

Turning the dimmer switch knob pivots the contact arm (or contact plate) on the variable resistor, increasing or decreasing its total resistance. When the knob is set to "dim," the variable resistor offers greater resistance so it "holds up" the current.

WebThe circuit ought to work: (Figure below) With the gate swapped to MT1, this circuit does not function. However, if this circuit is built, it will be found that it does not work! The load will receive no power, the TRIAC refusing to fire at all, no matter how low or high a resistance value the control resistor is set to.

WebMay 31, 2024 · The triac outputs can be used in many applications to switch 24 VAC on or off for external loads such as actuators, relays, or indicators.
