How to choose the SVTA power controller for a transformer?

  1. I wonder if the SVTA4694 can be a good choice to control a transformer with 15 amps on the primary?

    Good morning
    You are right: SVTA range is designed for tranformer control.
    The starting ramp must be adapted to the load (of the transformer) to avoid current pulse.
    In the worst case with a full conduction switch ON, the current can increase up to 30*In, in your case, the SVTA4694 will support this current pulse according to Non-repetitive peak overload current, but the margin of safety with this thyristor rating is not very important.
