why the current become zero after passing a step up transformer?

[izzu91]

i create an square wave inverter and i make pass trough a low pass filter to convert it to sine wave, and i want to step up 12 vac(after filtered) to 240 Vac by undergoing a step up transformer, but , at last , i get current at zero value but not for voltage. all this simulation i did it on Simulink (Matlab). here i attached a image of my simulation.. help me

There is no load on the transformer to draw current.

no, i tried it with load, but doesnt help me..

Chuckey is correct, there is no current drawn from your 12v to 240v transformer, hence you see no current.

We can hardly discuss the operation of circuits you didn't show.
