Hi,
A bridge circuit is used. Two IGBTs in the bridge are simultaneously turned on at 50/60Hz and then the other two. Then, the output becomes an AC waveform at 50/60Hz. This is for square/quasi sine waveforms. For sinusoidal it's slightly different, in the sense that the IGBTs are turned on at different duty cycles at a specific time period (of the modulation frequency).

Hope this helps.
Tahmid.

Hi,

You can use a push pull circuit with Igbts to generate DC to AC. IGBT means Isolated Gate Bipolar Transistor.

This active component combines the power of FET and the durability of Bipolar transistor.

Cheers.
