Hello. For a school project I am building a Cockroft-Walton voltage multiplier designed to be run on 120V conventional household current. I am aware that the output is DC, but does the waveform have any peculiarities if I run the multiplier on sinusoidal AC? It seems like I would only get a linear output DC voltage if I fed it a square wave. Also, what advantages are there to making a full wave circuit instead of half wave? My only objective is to make a really pretty spark, and I am curious what benefit the full wave version brings. Thank you very much in advance.
