transformer

Hi, This is the schematic of a ccfl driver I "reverse engineered" by looking at the board. I am pretty sure the schematic is correct. J2 represents the primary of the transformer. Can anybody help me figure out which pins of the primary correspond to which winding? Thanks

May not mean anything to non-uk people! So anyway, looking through eBay listings I keep seeing site transformers (if you don't know, they are used on building sites etc to provide 110v cte power for tools), sometimes very cheap, and keep wondering how easy or hard it would be to take one apart...

As I know transformer laminations should be insulated to minimize eddy current. If so, why microwave oven transformer E I cores are welded together!

Hi all. I recently purchased a (obviously) second hand CRO oscilloscope. It worked fine for a couple of days, I was just getting used to it. Then one day, I left it on for 10 mins or so with both traces active on screen. A while later, I heard this high frequency hiss, so I switched it off. The...

Hi everybody, I am not only new here but have little to no clue about electrics/electronics, but a question, where I am hoping to get some ideas/answers. I have purchased a winch enabling me to pull our boat on a trailer in and out of the water on a ramp. The winch requires 12V and I would like...

Hey guys, This is my first post and I am happy to have found this website. I am currently working on a project using a PCB and jumper wires to make a 48v Phantom Power supply to be used with multiple condenser microphones. To make a long story short, I found a "mostly" detailed post on another...

The wall power is rated at 50 to 60 cycles per second. I want to feed a circuit with that energy (50 - 60 Hertz) and obtain a higher frequency output, pure sinusoidal wave. Preferably, it can be tuned from around 100 hertz to 30 kilohertz. The output wattage must be at least 300 watt.

I have a toroid transformer where the input is 230 VAC and it has 2 output each one rated at 40 VAC. Can I feed the 40VAC part with 230VAC and get >1 Kvolt output?
