Hello,
Could you please advise how the capacitance of 1 uF of C1, C2, and C3 next to each leg of the inverter of motor drive stage was determined? I am concerned whether they are too small for 20A current current. How would I know whether it is appropriate? Should I measure dv/dt across the DC link or across the MOSFET drain and source? Any ideas would be greatly appreciated.
Thanks,
John
