STM32F1xx microcontroller - several peripherals

used to manage the STEVAL-ISV003V1

demonstration board

The STEVAL-ISV003V1 is a 250 W dual stage converter digitally controlled by a 32-bit

STM32F1xx microcontroller to allow operation in grid connection while performing an MPPT

algorithm on the PV panel side. Several hardware peripherals, embedded in the

microcontroller, have been used to control the system and to allow communication with an

external unit. In particular, the power board is made up of two sections, a DC-DC converter

and a DC-AC converter. Figure 3 shows an overview of the main blocks used to design the

system.
