My observations of wobbles and spikes at 0 crossing are the wobbles are the result of incorrect value choke. Sharp spikes that I experienced were from the MOSFET drive not being up to driving the number of MOSFETs I was using. Also a out of spec MOSFET could cause spikes. Since I started using Totem pole transistors to drive the MOSFETs and a different supplier of MOSFETs this problem has not come up again. I am waiting on some IR2010 driver chips to arrive to see if they make any difference compared to the IR2110s. There are only 10 types of people in the world: those who understand binary, and those who don't.
