isolation transformer

I understand what common mode transients are. What I don't understand is why they are important at a deeper level. This Ti app note says that: What I don't get is why any of that would happen. Also are there more other/further consequences of insufficient CMTI Here is what I understand about...

I really appreciate if someone can help me a bit with this project. Its a half bridge topology DC-DC converter that takes 12V on the Input and transphorms it into a simmetrical 80V output (Maximum). The output voltage will be adjustable from ±18V to ±80V. I am using the SG3525 IC for this...

Hi All, I want to mess around with some AC circuits on a breadboard with my oscilloscope. No real projects in mind, I just want to get some hands on experience with some AC to DC circuits. The main problem is the Mains problem. I obviously don’t want to plug a breadboard into the wall, so I was...

I have a small Block FL4/12 transformer laying around for which I expected the output to be 12V RMS on secondary side but I'm measuring different values. It is a dual winding transformer on primary as well as secondary side with ratings 115V for each winding primary side and 12V for each winding...

Hi all, I'm interested in assembling a circuit that will be capable of CONVERTING 220V TO 5V@2A 10W (Edit: AC TO DC) The issue is that I manage to find only PRICEY, HUGE TRANSFORMERS like this. I know there are small circuit (example) available for purchase, so my question is - Where can I...

I'm building my test/repair bench (I'm a hobbyist). I've been reading and watching videos on needing a isolation transformer to protect test equipment (oscilloscope) , and the tester (me). I'm wanting to know that best route to take. Should I get a single output isolation transformer or a...
