    3-phase PWM Inverter with variable voltage frequency

    three phase pwm inverter thanks Mr.Cool for reply.. i'm use Orcad 9.2.. "the hard part will be how to deal with the floating grounds of your system. each "upper" switch in your bridge has its reference to the center node between teh 2 switches. you know what i mean?" -->> i don't understand...
