Hello everyone

I am facing some problems with my project. I m trying to create a three phase system but i ve undesirable results at the output. I get phase angles distortion between three lines like 20V, 450V and 280V in order to get 400V system. Any device that can automatically detect and regulate lines angles to obtain pure 400V 120 degree phase system?
 

Would like to help but...your request is totally ambiguous and confusing.

For instance: "I m trying to create a three phase system" What does this exactly mean? Are you generating or synthesizing the three phase waveforms?

Or for instance: "I get phase angles distortion between three lines like 20V, 450V and 280V in order to get 400V system" What does this sentence actually mean?

Can you post waveforms, schematics, photos, something?
 
well. i have three inverters 48vdc input and 230vac output. how to make them work as a three phase system ( L-L ) 400V?
 

Obviously the three inverters must be synchronized, usually driven by a common signal generator. For details we need to know how the inverters are driven (e.g. digital signal generation, analog pwm generator, etc.). Examples of three phase inverters have been published at edaborad and an be found on the internet.
 

Indeed, a master clock with three waveforms displaced 120 degrees from each other to synchronize the three inverters is the very first requirement.
