Laminated core vs toroidal

[Deepdark]

As the titel say it. More precisely, I'm working on a power supply to feed 24v and 48 and I'm looking at some options. I've already looked at the option of using a dual secondary toroidal, and my goal is to feed the phantom power on a different winding than the b+. So here is my question, what if i use, for exemple, a 24v Laminated core pt for the 24v rail and a 48v Laminated core pt for the phantom? Mounting on a nice pcb, etc. It remains cheaper than getting a custom 24-48 toroidal. I already have looked for all the voltage doubler things, etc. I'm just curious about that option. Is Laminated core pt more prompt to electric field than toroidal?

You mean EL-core: Toroids are laminated too.

And yes, EL-cores usually have an order of magnitude higher magnetic and electrostatic stray fields than toroid designs.

But EL are also much cheaper, specially in small VA's, so depending on your actual design it may be perfect anyway..

You mean EL-core:

You mean EI cores.

Yeah Sorry el-cores. Thanks guys
