Hi all,
sometimes we introduce an air gap into a transformer so as to not saturate the core as quickly when trying to store energy up in the primary (i.e. flyback converters).
Can somebody help clarify to me what happens to the stored up H field in the primary coil during the off cycle? How does this H field persist such that it pushes the flux through to create the required voltage emf in the secondaries to create electrical power.
I realize what I just stated seems like the answer, however I do not have a 'clear' visual image of this.
Any help would be greatly appreciated. See page 5 of attached app note for a clearer picture of what I am after.
Thanks
