GOOD MORNING GUYS, I'M DESIGNING A VF Control of 3-Phase Induction Motors. I'M USING THE POWER CONTROL MODULE THAT THE PIC18F1330 HAS, AND THE IRS21084 AS THE DRIVERS THAT COMMUTE THE MOSFETS. I ALREADY HAVE THE SINE TABLES OR THE OS FOR THE MICROCONTROLLER AND WORKS GREAT AS AN ONE PHASE DRIVER.

I HAVE AN INCONVENIENT TRYING TO GENERATE A 120DEGREES PHASE ANGLE BETWEEN THE PWM'S, THESE PWM'S ARE GENERATED BY THE PIC'S HARDWARE. SO I NEED SOME IDEAS IN ORDER TO GET THE PHASE SHIFT I WANT TO

THANKS
