Very Low Ripple-Noise 220VAC to 15(12) VDC 3A Flyback AC-DC Converter
This video presents the design of a low noise AC to DC, 75-230VAC to either 15 VDC or 12VDC flyback converter. You can switch between 15VDC and 12VDC by changing the upper voltage divider resistor value from 27K for 15VDC to 20K for 12VDC.

TRIAC AC Control Using Arduino || Phase Angle Control || Light Dimmer
zhlédnutí 3,6KPřed 2 lety
This video shows you how to control the brightness of AC light bulbs using a Triac. This is done by reducing the amount of voltage that is applied to the bulbs. A potentiometer is used to change the firing angle of the Triac. An interrupt which is generated from the zero crossing through Arduino is very important for this control.

    surely recified ac should be 100Hz?

    • @smoothengineering42
      @smoothengineering42 PĹ™ed 2 lety

      NO, it can't be 100Hz, both the period and frequency remains 20ms and 50Hz respectively. What only changes is the negative part of the wave gets shifted to the positive side .

    Very well done... also what about the Ac diac. What diac is used.. or was that for reference?

      The Ac diac used is MOC3021, sure I will link the code in the description

      @@smoothengineering42 I'm trying to control a small 300w 110volt heater for a small hot plate for soldering. But that takes 110v, and in your circuit your using a transformer to reduce mains volt to 18v ac. How would I go about hooking in the 110v heater...

      @@jeremyboven you can use current limiting resistors at the input to the optocoupler to limit the forward current between (10 -50 )mA and forward voltage to less than 1.5v. The current limiting resistors should be on both N and L before connecting to the bridge ratifier (use resistors values between 4.7 to 10k, since you are using 110V, 1 watt resistor or higher). Between the optocoupler and bridge rectifier use resistor value of 360 ohm or less instead of 1k as in the video, to keep the forward current (10 -50 )mA . The values (10 -50 )mA and 1.5v or less is from the datasheet of 4N25
