TMS320F2800137: F2800137Running PFC (TIMD0208) open-loop inverter problem

Part Number: TMS320F2800137


Hello, expert

Run PFC program experiment 6 (open-loop inverter), in the function TTPLPFC_ In PWM Driver(), TTPLPFC_ PWM_ SwState. enum_ PWM SwState is always PWM SwState_ DefaultState, global search, no TTPLPFC found_ PWM_ SwState. enum_ PWM SwState from PWM SwState_ The defaultState changes to another state, and PWM does not have waveform output at this time. May I ask if TTPLPFC can be changed here_ PWM_ SwState. enum_ What special conditions are required for the state of the PWM SwState variable?


If you add statements according to the following diagram, it will generate waveform output, but I am worried that there may be something wrong

thank you! 

best regards !
