switching pulse delay

i want my mosfet with gate signal block to start switching at 50kHz after 0.5 s of delay. is it possible to do in PSIM? if yes then please if anyone can guide i will be highly grateful

have a look at the attached simulation.

I show a general method using a “mux” element that changes state at 0.5s using an integrator to track time. You could use the MUX on either the carrier waveform or the modulation. You can also “and” the output (PWM) with “0” using the same integrator circuit to change to a ‘1’ after a specified period of time.

I also show how the “Tstart” attribute can be used to keep the carrier waveform at zero until a specified time.
