There are 3 ways (or more )
1. Couple a single phase motor with 3-ph generators (this method is not much practical )
2. You can go for Ernoconverter .
Let me explain ……. Suppose you are having a 3ph induction motor . Connect it in delta configuration . Apply 1ph supply to any of it's winding amd gove an.external starting torque . Now you can.see there is a vtage across each winding . So , thus youay have 3ph power from single phase supply . But this system is too much unstable ,that's why it is notuch reliable .
3. Now here is the sophisticated way out . Just connect a single phase rectifier with a 3-ph imverter . This method is too much reliable as you can control the output voltahe and frequency very easily even you can add remote control ( if interested ) . Here is the circuit diagram ……
My phone camera is not too good as well as my handwriting . Hope you understand the picture and I haven't shown firing circuit for simplicity . You can control the firing pulses using microcontroller or arduino.
