Overview
This reference design deals with the average current mode control of Power Factor Correction (PFC) on the NXP® MC56F8013 digital signal controller (DSC).
- The application is written for MC56F8013, but can be easy ported into the other members of the MC56F80xx family according to application requirements
- Both fast current and slow voltage loops are implemented digitally using the DSC and the PFC power switch is controlled directly by the DSC
- Using direct PFC, we can achieve much better dynamics of the system so the solution is cost-effective
- The example of such PFC implementation into 3-phase single shunt ACIM vector control is described in this reference design
