One way is you can convert single phase AC to DC (rectifier) and then convert again to three phase AC by using inverter. I assume the energy from single phase side enough to drive three phase motor.

yes eiphan i have this idea, but i don't have sufficient data related to this.....can you further help me.. i have the block diagram related to my project idea here it is

From what I see from the diagram, you may want to use PFC rectifier circuit with thyristor control or PWM IGBT control. I recommend IGBT depending on the rating of your system. First, I suggest you to make SM rectifier to regulate the DC link voltage while maintaining power factor to near unity. Once it is done, you can proceed to implement three phase inverter with whatever control scheme that you like. again I recommend IGBT for switching and you can even implement regeneration. you might have appropriate controller for the system. I want to refer to power electronics book written by Ned Mohan. The book can explain this idea. Please let me know if you need any more help.
I don't think it can be called as frequency converter. Please do correct me if I am wrong as I am not power guy. He will be still using the same 50Hz or 60Hz. He wants to convert the single phase 230V to 440V diveded into 3 phases using IGBT. This is normally done in UPS, inverters etc for delivering 3 phase from a single phase if I am not wrong.

After all, the device will let the user easilly change speed (and thus frequency) of the AC motor. The user just decide to not take advantage of the other nice features of the device.
Gm sir,
my name is nitin.
I am working on the same thing but initially I want to convert 415v AC to 700 dc for the rectifier circuit. I have tried this circuit using IGBT circuit using two pole in Simulink matlab.
but I am failing to do so why I don't know.my parameters and specification of the Simulink model is
Vin = 415V(ac),Vout =700(dc).I have used feedback path to control the output regulated to 700.
I have used PWM (4000hz) to drive first two igbt and next two igbt with the same frequency of the input voltage ie 50 hz.
I have used PI(proportional integral) controller. but I don't know how to tune that PI controller.
I am new to Simulink.
please help I will be thankful to you.
