A bias winding is needed in order to utilize the over-voltage protection function.
The transformer can be built or purchased according to these specifications:
The minimum operating frequency during normal operation is that calculated above but during shutdown the LLC can operate at right above ZCS boundary condition, which is a lower frequency. The magnetic components in the resonant circuit, the transformer and resonant inductor, should be rated to operate at this lower frequency.
