5.2.1 ADC Interrupts

PFC and FOC control loops are executed in their respective interrupt service routines. As PFC control loop executes at a faster rate than FOC control loop, the interrupt service routine for PFC has a higher priority over FOC.

Figure 5-1 shows the timing diagram of the integrated PFC and Sensorless FOC system. Figure 5-2 through Figure 5-4 show the state flow diagrams of the integrated system.
