Hi all,
I'm reading the document HVPSFB_User's Guide_v1.1.pdf from controlSuite.
As far as I understood, it is necessary to call the ISR or CLA in PCMC twice as often as in VMC.
In this document the used MCUs are TMS320F2802x and TMS320F2803x with a Type1 ePWM - Modul.
My question is:
Is there an easier way to implement the PCMC with Type4 ePWM -Module?
The PWM_PSFB_VMC_SR_Cnf.c config file seams to be the same.
Thank you.
Hi,
Yes, there is an easier way to do implement this with Type-4 PWMs. There are changes in the action qualifier (AQ) and the trip-zone (TZ) sub-modules that allow this. You can generate T1/T2 events in the AQ based on the same DCxEVT (comparator output based) or TZ input event. These T1/T2 events along with the rising edge delay (RED) and falling edge delay (FED) mechanisms in the dead-band module can be used to provide dead-band (which is mainly handled by the ISR in the 2802x/3x version). Please see below for an example implementation.
I hope this helps.
