What I was really interested in is understanding how different
configurations effect ripple. Unfortunately, since I'm not an
engineer, I'm mostly reliant on finding existing models and piecing
things together. But even creating a simple equivalent circuit is a
little beyond my abilities. Anyway I suppose I'll just build a basic
78L15AC/79L15AC circuit and see what happens.

Thanks,
Mike
