inverter single phase 230v ac to 3 phase 400v ac

Hi, I.m trying to make a simple pwm project of an inverter, (with simscape) which receive as input 225v ac in single phase and as output I would like to obtain 389v ac(225*sqrt(3)) for phase to phase voltage.

But, as output, from the 3 lines of the six mosfet, the phase to phase voltage measured is equal to 223v ac and not 225*sqrt(3).

Can anybody help me to find a solution?

Regards,

Agostino

The first issue is that you are feeding a constant duty cycle into each arm of the inverter. This does not generate an AC signal. You need to do something like this: https://www.mathworks.com/help/sps/ug/ac-dc-ac-converter.html
