2.2 Incremental Builds

This project is divided into three incremental builds. This approach provides the user with a step-by-step method to get familiar with the software and understand how it interacts with the BL PFC hardware. This approach also simplifies the task of debugging and testing the boards.

The build options are shown below. To select a particular build option set the macro INCR_BUILD, found in the BridgelessPFC-Settings.h file, to the corresponding build selection as shown below. Once the build option is selected, compile the complete project by selecting rebuild-all compiler option. Next chapter provides more details to run each of the build options.

Table 2-2 Incremental Build Options for PFC
INCR_BUILD = 1Open loop check for boost action and ADC feedback (Check sensing circuitry)
INCR_BUILD = 2Open voltage loop and closed current loop control of BL PFC
INCR_BUILD = 3Complete voltage loop and current loop control of BL PFC
