Inductive wireless charging

[Mike_85_]

Hi, i am trying to do my study project inductive wireless charging. I have try to do a circuit but i its not working  .I am new in multisim, so i need help. Some components that i need there arent in multisim, so i choose something similar. First of all some components have many variations, for example LM393N, LM393M. what does actually mean?

About the inductive coupling i dont know how to calculate the value of the inductors. The number of the primary coil is 210 turns and for the secondary 9 ( 120v to 5v )

Any help is will be invaluable to me

If you need more details ask me

Thanks in advance

Hi Mike,

Don't worry about the last letter behind the part, these letters indicate the physical package like a surface mount, through hole and what size etc...  

Attached is a SPICE manual, go to page 222 it explains the mutual inductor coupling.
