| MPWM Motor Control (PWM Problem! ) |

Dear,
I'm trying to program a dsPIC30F4011 to control an AC induction motor using the PWM outputs in a complementary way but I'm not getting any results and no signal on the output PWM.
See complete code below:
I need to know where I am going wrong ... : 
Thank You.
| Code: | #include <30F4011.h>
#FUSES WPSA8
#FUSES WPSB1
#FUSES XT_PLL4 //External Clock mode with 4X PLL
#FUSES NOCKSFSM //Clock Switching is enabled, fail Safe clock monitor is enabled
#FUSES BROWNOUT //No brownout reset
#FUSES PWMPIN //PWM outputs disabled upon Reset
#FUSES WRT //Program Memory Write Protected
#FUSES MCLR
#FUSES BORV42

There's too much code with no guidance for me to even start looking at it.
Or maybe you're the first with the problem, and you can help the rest of us.
In twelve days, what debugging have you done?
May I suggest you break the code down, and attack it one small chuck at a time.
Sorry, can't help further.
