How to Connect Grounds in an Isolated Power Supply PCB Layout
Y-rated capacitors are a good choice here for higher voltage/current designs. You can do this easily in your schematics: just locate the component you need for your capacitor, and then bridge the ground nets with a direct connection. The typical place to do this in the PCB layout is close to the transformer.
Transformers (Part 1)
Notice that it is connected only to a portion of this transformer. Now, what will happen is that you''ll have a flux that is applied here by the voltage and that will be transferred to the rest of this inductor.
