I am using xmc1300 development board for PFC stage in 3.4kW onboard EV charger. In the software for PI voltage control loop I have to set the max power limit as 3.4kw. This power limit is also used in duty cycle calculation for MOSFET gate signal. The max dc bus voltage at LLC stage is 64v and the max current rating is 53A. How to scale this 3.4kW power limit , so that I can use it in the software calculations. I am using DAVE 4.4.2 VERSION.
Solved! Go to Solution.

Hi @Rakesh_rp ,
You can try changing the P_LIMIT_3000 ( 3050u) to P_LIMIT_3400 ( 3450u) to scale the power limit to 3.4KW
Please find the image for Q format calculation.
For Scaling up to 3.4 KW please change the respective current and voltage values within the software. Please ensure ADC configuration to measure current and voltage to scale up to 3.4 KW from 3 KW.
Thanks,
