I observed spikes on output of AC-DC converter in oscilloscope (image attached), when I switch OFF or ON of AC fan as per connection shown in block diagram. Here I did not connect earth. We connected Phase and neutral only.
I observed not only in our power supplies, almost all power supplies even in Lamda, Meanwell, etc.,
Here I am attaching image showing that spikes on 24V output. Maximum peak was 36.9V
What could be the reason? What is the solution to solve this?(Please visit the site to view this file)
