AC current / volatge with a mosfet in Ltspice

[ernd59]

Hi,
my Voltage Multiplier Simulation does not work properly the first transformer is working just fine, the second one does not really seems to work, for the second transformer i tried to creat AC current with a mosfet, but i think I am doing it wrong :/, can you give me some tips how to creat AC current with a mosfet in Ltspice.

Is there a reason that you have the transformer and switch there in the middle, instead of continuing the multiplier ladder?
