Difference between boost inductor and flyback inductor?

AI Thread Summary
A boost inductor is a two-terminal inductor used in boost converter circuits, while a flyback inductor is a four-terminal device that includes a transformer for isolation and voltage transformation. The flyback inductor operates similarly to a boost inductor during magnetization but utilizes the transformer during demagnetization. This allows for additional functionalities such as voltage conversion and electrical isolation. Understanding these differences is crucial for selecting the appropriate inductor type for specific applications in power electronics. The distinction between these inductors impacts their operational capabilities in various circuit designs.

What is the context of the question?

And you normally need a transformer for flyback operation...
 
A boost inductor is a two terminal inductor.

A flyback inductor is a four terminal device. It consists of a two terminal inductor with an ideal transformer connected across it.

You magnetize it just like a boost inductor. But when the inductor demagnetizes, it does it through the transformer allowing you to provide isolation and transformation.

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...

Thread 'EMF (Electromagnetic Field) & EHS (Electromagnetic Hyper Sensitivity)'

Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
