I would like to ask question about LLC vs AHB
For Pout >140W/200W. Why LLC is recommended to use in common usage, rather than AHB?
is it related to LLC with 2 output mosfets share the current stress, but AHB with 1 output mosfet only? Or other reason (eg efficiency data) ?
Most LLC mass production charger is with “Extra” resonant inductor for stability inductive region ,
but most AHB mass production/demo board charger is without “Extra” resonant inductance, just use transformer leakage inductance to do so.
Why AHB can use transformer leakage inductance as resonant inductor? But LLC can not?
Why AHB can accept this relative high tolerance of leakage inductance in design, but LLC can not?
Thanks a lot
