Creating PWM in Matlab used to fire three mosfets in parallel

04/18/2009 4:09 AM

hi

I would like to know how to create a pulse width modulation using MAtlab. I have thus far generated a saw tooth and compared with a sine wave however I do not know how to control the duty cycle.

My circuit contains the following:

3 phase ac source, 3 mosfets in parrallel and a resistor and inductive load.Source is 17Vrms, 27Hz.

Function of circuit: Convert 17Vrms to 14V dc

This sounds like a homework problem.
