ZVS Driver, Intermittent Operation Question
Posted: Mon May 16, 2016 8:58 pm
I have built a ZVS Driver, using a 4000 turn secondary from amazing1.com, and a common schematic for a ZVS from the internet. Photos/schematic below.
The driver works intermittently - specifically, when I apply power (13.8v at 25 Amps available) and POKE the primary coils... physically poke them. Then the unit jumps into action and I get an arc at the output of the flyback. Video is here:

Below are the images of the driver PC Board & schematic. Can anyone help me, based on the information presented, determine if I have to increase/decrease the number of turns on each primary section, or if I have a capacitor problem, or...??? I have tried opening the space between the coils as well as closing, and increasing the air gap between the two halves of the ferrite core of the flyback, to no avail. I'm not really sure why I would get arc only after poking the primary.
When I do get an arc, my current draw is only about 2 amps... much less than I was expecting.
Thanks for any guidance or feedback... no pun intended...
