Conversion ratios (see
This routine is called by the IRQ of DMA1_CH_1 that is generated after two
completed ADC conversions (see
Calculates mean of Vdc.
Performs a soft-start if the PFC status is PFC_STARTING or a software limitation if
an overcurrent or overvoltage incident occurs. After this, the PFC status switches
to PFC_RUNNING.
Manages the software limitation against overcurrent.
Manages the software limitation against overvoltage.
Performs a voltage PI every 400 cycles.
Performs a current PI every cycle.
Updates the duty cycle of TIM3 CH.4 and CH.3.
Calls CHECK_PROTECTIONS.
Returns the value of PFC_STATUS_FLAG.
Returns the value in volts of the DC bus voltage.
Returns the ADC’s converted value of Vac.
Returns the ADC’s converted value of Iac.
Returns the ADC’s converted value of Vdc.
