How to decide maximum operation frequency of MOSFET with varying duty cycle.
 

Does not effect duty cycle to frequency. I think you are not clear with your question.

Commonly MOSFET usable frequency is 1k to 100k
 

Switching losses increase with frequency and is probably the dominant factor.
 

Check your mosfet ontime and offtime delay and add both values. Your pwm frequency should be more than delay times. If you set limit of frequency some far from datasheet value it will be so safe.
