Digital PFC at work
Once the board has been reset, and if the firmware is correctly loaded into the Flash
memory and the PFC power board is waiting for a mains insertion, the LCD display should
show the following.
Figure 36. LCD after startup
If after the reset the screen is blank, this means that the firmware has not been correctly
downloaded into the memory or that the microcontroller has been kept in a halt state by the
dongle. First check if the microcontroller is in a halt state. Remove the JTAG dongle from the
connector and press the reset button. If the screen is still blank, you will have to compile and
download the firmware again. If the system has been connected correctly, after the mains
has been inserted the MCU will detect this condition and will launch the digital PFC and
protections.
The LCD display should now show the following.
