inverter demystified

there're some weird schematics up in the web as someone uses a transformer to input 12V squarewave and it outputs 153V one ?? -- i yet haven't figured out a transformer parameters for this trick

here's some tests that do simulate at least in more realistic -- as i see it ?

a sine test ::

a square wave test ::

is basically DC/DC -- with what to use for alternating the OUTP = don,t care -- a "programmed" resistors in this case
