Hi,

I am using TI F28027 to generate phase shifted PWM to drive HVPSFB,  following the PWM_PSFB_VMC_SR_Cnf and control suite demo.   I can generate shift PWM in fix phase angle, But I can not change   pahse shifted and deadtime in real time model  through  extern volatile long *PWMDRV_PSFB_Phase1; extern volatile int16 PWMDRV_PSFB_DbAtoP1, *PWMDRV_PSFB_DbPtoA1;.  How can i do with it? how to make sure DPL_ISR works well?

 Thanks

Nick
