Phase angle control using Arduino useful 1

Submitted below ac load management by Phase angle control using Arduino by delayed triggering to opto-coupler(U3)  interfaced triac (U4) for single phase load control using Arduino nano. Proteus file and the code for simulation are available at the bottom. For video watch at down below or use this link https://youtu.be/VpHoE_2MlEo Circuit Explanation for Phase angle […]

AC chopper

Controlling AC power by delayed firing angle control is a very old and traditional method. Simple example is our electronic fan regulator. But this has one major drawback that it generates a lot of harmonics (62%THD)as compared to a chopper(2%THD). Presented below a chopper that is much more efficient. . Please watch the video
