pic sinusoidal pwm

Hi I am working on Sinewave interter.I am new to this can any one help in developing sinusoidal PWM using micro controller.Give me some IDEA plesae



thanking you....
 

Take 1% PWM as the -ve of the sine, 50% as zero level and 99% as +ve of the sine. Use a sine table to load the CCP registers.

Hope this helps

Cheers
