3 Procedure for Running the Incremental Builds

All software files related to this C2x controlled BL PFC system i.e., the main source files, ISR assembly files and the project file for C framework, are located in the directory …\controlSUITE\development_kits\BLPFC_v1.0\BLPFC. The projects included with this software are targeted for CCSv4.

CAUTION:

There are high voltages present on the board. It should only be handled by experienced power supply professionals in a lab environment. To safely evaluate this board an isolated AC source should be used to power up the unit. Before AC power is applied to the board a voltmeter and an appropriate resistive load (only) should be attached to the output. This will discharge the bus capacitor quickly when the AC power is turned off. The board has not been tested with electronic load and so it should not be used with such load. There is no output overcurrent protection implemented on the board and so the user should take appropriate measures for preventing any output short circuit condition. The BLPFC board should always be started with 110Vac (60Hz). Once the board is up and running the input voltage can be changed to any other voltage within the specification.

Follow the steps in the following sections to build and run the example included in the PFC software.
