I designed an LLC SMPS using a PIC microcontroller.
It simply used an opto feedback and applied a high frequency if voltage was correct and a lower frequency if voltage was too low.
Worked very well.
I had an over current detector on the mosfets.

Since the subject of this thread is discussed in other threads in these fora, I suggest readers follow other more mature threads which have already tried and tested schematics. The following link is about a full bridge SMPS driven directly from rectified 230V AC mains.
