Multisim AC PWM

[tank27]

I am attempting to regulate a 50Hz ac waveform with PWM in Multisim10, but having difficultly creating a pulse train for each power transistor.

I attempted to place pulse voltage supplies in parallel with different offset times but this wouldnt simulate.

How do I create a pulse train for each transistor that misses the opposing cycle?

Hi,

Have a look at this knowledge base, I hope this is useful.

Thank you for the speedy reply but this tutorial isnt applicable to my circuit.

At its basic level all I am trying to do is control the on time of a switch.

Note the pulses will have many different widths and stay off for the opposing cycle.
