Hi guys,
I'm in the process of trying to simulate an interleaved boost converter in LTspice but I'm having trouble with the simulations.
As an example, in this picture they have the AC line input with a different ground:

If I go to a really simple case and simplify it to a single boost, I get:

It seems like I am unable to boost the input voltage at all (it's actually a few voltage less on the output than on the input). Is there any way to compensate for this to make the simulation accurate? Please pardon my lack of knowledge, but is this referred to as a floating ground?
Any suggestions?
Thanks!
