AC dimmer explained| Design your own dimmer PCB for Arduino| Phase angle control using TRIAC

TL;DR

Learn how to design and implement your own dimmer circuit using Proteus software, including the internal workings of the zero crossover detector circuit.

Transcript

hey guys today in this video we are going to design our own dimmer circuit and we will implement it on proteus will check its response whether it will work or not but in our previous video we have interfaced a robotnine dimmer with node mcu and we took help of blink app to control the brightness or you can say team a filament lamp and in this video...

Key Insights

• 🌉 Designing a dimmer circuit requires components such as a bridge rectifier, optocoupler, resistors, and an Arduino.
• 0️⃣ Zero crossover detector circuits are used to detect zero crossings in the AC signal and trigger the dimming process.
• 🎮 Triggering circuits, using optocouplers and TRIACs, are used to drive the AC load and control the dimming level.
• 😵 Delaying the trigger signal after a zero cross allows for different levels of dimming by chopping off portions of the AC waveform.
• 👻 The simulation in Proteus software allows for testing and verifying the functionality of the dimmer circuit.
• 😴 The programming part involves making changes to the pin numbers in the code and checking the preferences for compilation.
• 🎚️ A potentiometer is used to vary the delay and achieve different levels of dimming in the simulation.

Summary & Key Takeaways

• The video explains how to design a dimmer circuit using components such as a bridge rectifier, optocoupler, resistors, and an Arduino.

• The zero crossover detector circuit, which uses a bridge rectifier and resistors, is used to detect zero crossings in the AC signal.

• The triggering circuit, using an optocoupler and a TRIAC, is used to drive the AC load and control the dimming of the bulb.
