Original question:

TMS320F28335: TMS320F28335

TMS320F28379D: Using CLB and ePWM to control Multilevel Inverter

Mabonga Paul
Intellectual 340 points
Part Number: TMS320F280037

Tool/software:

Please advice me on how I can use the CLB and ePWM to control a t type five level single phase inverter as suggested in the thread. 

The inverter and carrier signals are shown in the diagrams below. 

Cody Watkins did suggest that the CLB can be used. 

Please advice me on how to implement it.

    Part Number: TMS320F280037

    Tool/software:

    Am designing a single phase 5 level t type voltage source inverter for an off grid system. The t leg mosfets switch at a high frequency (50kHz) and the other leg switches at the line frequency (50Hz) as an unfolder. 

    My issue is how can implement phase dispositon modulation technique on a c2000 microcontroller. The figure for phase dispositon modulation is shown below.

    Please advice me on how I can implement this modulation scheme on a c2000 microcontroller.
