我用PWM1A和PWM2B(波形一致)控制一对开关管，PWM2A和PWM1B(一致)控制一对开关管；PWM1A和PWM2B跟PWM2A和PWM1B为带死区450ns的互补；
现在的问题，
当驱动工作在断续模式下，每次开关段，关断时，PWM2A和PWM1B的驱动脉冲，总是比PWM1A和PWM2B驱动的多一个脉冲；如果拆开来看，就是PWM1B比PWM1A多一个脉冲，而PWM2A比PWM2B多一个脉冲；为什么不是成对出现？
从图中看，是否有一个波没有发出来；
PWM1A：黄色
PWM2B 绿色
PWM2A 红色
PWM1B 蓝色
代码配置如下：利用增减计数模式
EPWM_setActionQualifierAction(EPWM1_BASE,EPWM_AQ_OUTPUT_A,EPWM_AQ_OUTPUT_HIGH,EPWM_AQ_OUTPUT_ON_TIMEBASE_ZERO);
EPWM_setActionQualifierAction(EPWM1_BASE,EPWM_AQ_OUTPUT_A,EPWM_AQ_OUTPUT_LOW,EPWM_AQ_OUTPUT_ON_TIMEBASE_UP_CMPA);
EPWM_setActionQualifierAction(EPWM1_BASE,EPWM_AQ_OUTPUT_B,EPWM_AQ_OUTPUT_HIGH,EPWM_AQ_OUTPUT_ON_TIMEBASE_PERIOD);
EPWM_setActionQualifierAction(EPWM1_BASE,EPWM_AQ_OUTPUT_B,EPWM_AQ_OUTPUT_LOW,EPWM_AQ_OUTPUT_ON_TIMEBASE_DOWN_CMPB);
EPWM_setActionQualifierAction(EPWM2_BASE,EPWM_AQ_OUTPUT_A,EPWM_AQ_OUTPUT_HIGH,EPWM_AQ_OUTPUT_ON_TIMEBASE_PERIOD);
EPWM_setActionQualifierAction(EPWM2_BASE,EPWM_AQ_OUTPUT_A,EPWM_AQ_OUTPUT_LOW,EPWM_AQ_OUTPUT_ON_TIMEBASE_DOWN_CMPB);
EPWM_setActionQualifierAction(EPWM2_BASE,EPWM_AQ_OUTPUT_B,EPWM_AQ_OUTPUT_HIGH,EPWM_AQ_OUTPUT_ON_TIMEBASE_ZERO);
EPWM_setActionQualifierAction(EPWM2_BASE,EPWM_AQ_OUTPUT_B,EPWM_AQ_OUTPUT_LOW,EPWM_AQ_OUTPUT_ON_TIMEBASE_UP_CMPA);
