How to connect parallel AC flybacks
« on: November 21, 2020, 09:50:28 PM »
I am currently building a 14-stage CW multiplier. The HV AC power supply will consist of 2 identical AC flyback transformers connected in parallel for increased drive capability. The flybacks will be driven by a single ZVS driver. Is there anything special about connecting 2 AC flyback transformers in parallel for increased driving ability?

For the flyback primary coils I plan on winding an identical center-tapped primary coil on each flyback. The 3 leads from the 2 coils will then be wired in parallel and connected to the ZVS driver output.

For the flyback secondary coils, I just plan on connecting the outputs leads of each secondary coil in parallel.

Is there any problem with this approach? My only concern is that the 2 flybacks may want to oscillate at different frequencies. Is this a valid concern?

I see no issue.  Should work exactly as you intend.
