I'd like to know the role and the calculations behind the capacitors added to the HV-port and LV-port for the EVM board. Thank you

Hello,

Thanks for reaching out. Those are the input and output capacitors of the power supply. You might use the Power Stage Designer to calculate the capacitance values https://www.ti.com/tool/POWERSTAGE-DESIGNER .
