Specifications Digital Power Factor Correction This application exercises simple control of the Power Factor Correction (PFC) without motor control on the 56F805EVM board and the EVM Motor Kit. 1. Specifications Freescale Semiconductor, Inc... The Digital PFC application performs power factor correction for 3-Phase AC/BLDC High-Voltage Power Stage hardware without motor drive. This demonstration evaluates the basic algorithm of power factor correction for the current hardware implementation. The PFC software was designed for use with motor control applications; the Digital PFC application allows target memory configuration of RAM and Flash. The input power line must meet the following requirements: • • Input voltage value 115V and 60Hz Input voltage value 230V and 50Hz The applications run at 230V, 50Hz by default. To switch to 115V, 60Hz, comment this line in Digital_PFC.c: #define MILESTONE_OFFSET MKS_TO_TICK(570L) //For 50 Hz, 230 V And uncomment this line: //#define MILESTONE_OFFSET MKS_TO_TICK(1498L) //For 60 Hz, 115 V The Digital PFC application may be used in the Manual Operating Mode. The remote control functionality of the PC master software application is not implemented.

For more help with these commands, refer to the CodeWarrior tutorial documentation in the following file, located in the CodeWarrior installation directory: <...>\CodeWarrior Manuals\PDF\Targeting_56800.pdf If the Flash target is selected, CodeWarrior will automatically program the device’s internal Flash with the executable generated during Build. If the External RAM target is selected, the executable will be loaded to off-chip RAM. Once Flash has been programmed with the executable, the EVM target system may be run in a stand-alone mode from Flash. To do this, set the JG5 jumper in the 1-2 configuration to disable the parallel port, and press the RESET button. To enable the PFC conversion, set the RUN/STOP switch to the RUN position. If this switch was in the RUN position before the application started, move it to the STOP position first, then back to the RUN position. The USER LED should light continuously when the PFC conversion is enabled. To disable the PFC conversion, move the RUN/STOP switch to the STOP position, causing the USER LED to blink again.
