I am trying to understand how LLC converter works, in one of the forums, Eric said: "In resonant LLC the magnetizing inductance is used to determine what the resonant tank frequency is."
I am trying to analyze what is the role of Lm in the circuit. ( I read in monolithicpower website that says adding Lm is related to tank’s response to heavy load and light load).
But I don't understand how Lm can determine what the resonant tank frequency is?!
Could you please explain in more?
Thank you!
