Current and voltage protections
The digital PFC demonstrator includes the following.

●
With the exception of the hardware protection, all values that take part in the software
protection or limitation can be modified in the "PFC.h" file (see
A hardware protection against PFC overcurrent (14.3 A). The PFC is stopped when the
value of the inductor current goes above the value fixed by the hardware, in this case
14.3 A (see
A software limitation for a maximum PFC current (13 A). Each control loop PFC is
momentarily stopped if the inductor current rises above PFC_MAX_IL (13 A) and
restarts when the inductor current goes below PFC_MAX_HYS_IL (95% of
PFC_MAX_IL).
A software protection against output overvoltages (460 V). Each control loop PFC is
stopped if the DC voltage rises above PFC_MAX_THRESHOLD_VDC (460 V).
A software limitation for a maximum output voltage (435 V). Each control loop PFC is
momentarily stopped if the DC voltage rises above PFC_MAX_VDC (105% of
PFC_REFERENCE_VDC) and restarts when the DC voltage goes below
PFC_MAX_HYS_VDC (98.75% of PFC_REFERENCE_VDC).
PFC_REFERENCE_VDC is 415 V.
