Please can anybody help me about how to generate 120 deg phase shifted pwm waveform for ac motor control?

Depends on how you generate the "pwm waveform". The phase shift applies to the modulating sine waveform, not the pwm carrier. Assumed you are generating the sine by a lookup table, the 120 and 240 degree phase shift isn't but an offset to the table index.
