If you are going with AC drives then you don't need to build anything this is the beauty of AC drives, you just buy a toroidal transformer and pull directly from the secondary outputs. The only thing you need to do is decide how you are going to use the secondary outputs. This will be based on the spec of the Toroidal transformer you buy.

If your not sure what I'm meaning just say and I will explain exactly what I mean and provide a diagram showing how it's done.

Even building a DC supply using a toroidal transformer isn't difficult but does require sizing components correctly to give the required output. But the actual building or wiring side of it is very simple, you don't need to be an electrical Wizzard. Again I will happily help you chose the correct components when you know what you require and decide on using a DC supply..
I've helped 100's of people with Zero electrical knowledge build them so don't be phased it's easy enough.
