PWM setting wih DSP F28335

Hi, everyone

I am using the TMS320F28335 control board for the Dynamic Voltage Restorer circuit.

I am using the code generation functions that PSIM provides for F28335 Target.

I need a PWM signal that can vary normally in width, but after programming my DSP, I measured that the signal is abnormal. The duty cycle reaches almost 98% and does not change, which will cause my switch to burn out. How should I adjust my program?

I look forward to your reply.

Thanks,

LIN
