is there anyone has schematic of 3 phase inverter using MOSFET that successfully tested for driveing induction motor 220V?
i build 3 phase inverter using MOSFET IRFP460. but, the problem is i can't drive the motor.

I don't know of any inverters that can power 220V motors. A 110V inverter is useful for powering small appliances from a battery, but it is better to purchase one because of the complexity of their design. If you can't get the motor to turn, either the motor voltage or the frequency is too low.

the phase of frequency is right, 120 degree because i drive my inverter using 180 degree conduction.
i drive my 6 MOSFETs using IC IR2130. output voltage is 15 volt. everytime i drive my inverter with DC voltage above 15 volts, the output voltage is always 15 volts, no change. how can it be possible?
