six_step_pwm_commutation_python

If you need to get a six step pwm for three phase inverter using Python, you can use the following code which creates six commutation signals. Each output has 60 degrees lag with the previous one (p1, p2, p3, p4, p5, p6). The firing signals are issued over GPIO2, GPIO3, GPIO4, GPIO17, GPIO27 and GPIO 22 which are the first lower left pins of the second row of raspberry pi IO pins. Note that in practice as mentioned before, there are “hick-ups” or irregular flickers in the output pulses. If you are not required to have the duty cycle changes every 100 ms, simply comment out lines under While loop. The code compilation will be fine using "python3" in command line or Thonny in Raspbian Stretch (2019-04-08)
