For the second question, I think so, because the "Immediate Load Mode" is set, and TBPRD is set to TBPRD(Active), while TBPRD(shadow) is still 0. When I set it to "Shadow Mode", shadow TBPRD(0) → Active TBPRD, so the EPWMA and EPWMB outputs are lower. I should set TBPRD to 300 after setting it to "Shadow Mode".
