how to Generate PWM using Atmega32 for sine wave inverter [need help]

I am currently working in a Sine wave inverter project, and i need to generate PWM using microcontroller, for that purpose i have chosed atmega32, can somebody guide me from where to start and how to proeceed in writing code for pwm generation using atmega32, any response would be appreciated, thank you

Atmega has inbuilt PWM module (timer in PWM mode). use it to generate PWM. Read datasheet for more information.
