I am trying to generate PWM to control PMSM Motor with three phase inverter.
Configuration for each of the PWM Module A is given below(Using eFlexPWM).
Sub Module 0 - Complementary PWM
Clock source - IPBus Clock
Local Reload
Full cycle reload
PWM Reload at every opportunity.
Sub Module 1 - Complementary PWM
Clock source - Sub Module 0 Clock
Master Reload
Master Sync
Full cycle reload
PWM Reload at every opportunity.
Sub Module 2 - Complementary PWM
Clock source - Sub Module 0 Clock
Master Reload
Master Sync
Full cycle reload
PWM Reload at every opportunity.
I am using ADC End of Conversion Interrupt(with PWM Sync for Triggering an ADC) to reload PWM Registers.
With Sub Module 0, If i make it as independent PWM Mode, I can see PWM on the Pins.
But same does not work with other modules.
I have been working with eFlex PWM from past 3 Years with DSC Series Controller and didn't find any problem to generate PWM for three phase inverter. But, The same couldn't work with Kinetis Controller MKV46F256VLL. Can anyone tell where i am going wrong?.
Any help is appreciable.
