Hi all friends
I'm new on 3-phase SPWM inverter circuit and I’m work on micro-controllers for this target from microchip company . I chose “dsPIC33FJ16MC101” , But there are a series of questions for me:
1 - In a study to establish the SPWM signal, experts from 3 sine wave with a phase difference of 120 ° with a triangle wave with a high frequency compared , and the location of the intersection between signals( sine and triangular ) outputs PWM. Now I'm wondering in the micro- controllers that are capable of “MOTOR CONTROL PWM” such that I introduced above, the operation what is being done?
2- These micro-controllers have Class B-Compliant Fault Inputs, which are obviously importance. What is the task of this pin (The pin functions , Which part of circuits are connected)?
