Two-level PWM modulation [Copy link]

I have a question: When I use two-level PWM modulation, since the counter can only start counting from 0, in order to be compatible with the negative modulation wave in SPWM modulation, I need to move the triangle wave (carrier) and modulation wave up. How can I achieve this in the program? [img=0,24]file:///C:/Users/Administrator/AppData/Roaming/Tencent/Users/1351259622/TIM/WinTemp/RichOle/FC4AVD6Z68H_YPIM[BR6CMM.png[/img]
