hello ee_student

I am sure that you are not the only one to want a complete design!!
The basic principles for a three phase input three phase output and a single phase input three phase output inverter are the same. The only difference is that the single phase input unit has a single phase bridge rectifier and a much larger storage capacitor while the three phase input inverter has a three phase rectifier and a smaller storage capacitor. In both cases, the output voltage is limited to the input voltage unless an additional transformer is used.
Best regards,
