This workflow starts from power conversion requirements. This information is then reinterpreted in the application
specs that contain information linked to the MCU peripheral and the DPC application configuration.
On the basis of this information, an
STM32CubeMX project, properly configured and initialized, is provided. Then,
the needed DPC module is included and configured.
The
STM32CubeMX generates the development IDE project. The MCU is directly flashed through the IDE or
STM32CubeProgrammer . At the end of this operation, the DPC application is tested and debugged through
STM32CubeMonitor . The digital power converter firmware is then released, if compliant, and the DPC is adapted.
The STDES-PFCBIDIR reference design power converter allows managing the two-direction energy flow. The
figure below shows the algorithm schematic diagram of the implementation in the AC-DC rectifier application and
DC-AC inverter application.

The figure below shows the basic representation of the execution flow. A current decoupling control well fitted
for this application is used. This allows managing the bidirectional energy flow in terms of AC current without
discontinuity in the operation of the high dynamic inner loop. Only the outer loop is adapted to ensure the correct
operation for both loops.
