Hello everyone,
I am designing a controller for 2 hub motors and I am using IRFP4468 MOSFETs.
There are 8 MOSFETS in total but only 4 working at any time since I am using them as H-Bridges.
I am new in the world of PCBs. I already finished the PCB design but I need to design a heatsink for it.
I tried calculating the heat load, I got the following
I=7.5 A through each H-bridge
V=48 V
q=123.6 W
Osa=0.3 C/W
Did I do the calculations correctly?
Now I need to figure out if I need a heatsink and if yes, how big do I need it to be?
