Hello,

Is it possible, to have all 3 currents as an input to the "Clarke Transformation simulink block" instead of only two.

If not, is there any workaround?

Thanks in advance!

You have to design the Clarke block by yourself since the Clarke in c2000lib of Simulink just supports two inputs by default. Actually, you only input Phase A and Phase Currents to the Clarke block that has the same convert result as three inputs since Ia+Ib+Ic=0 in 3-phase motor control.

Thanks for the answer. The reason I want to have 3 current measurement is that with two the error sums up. Thats why 3 phase current measurement is better.
Does anybody designed such a block?
Thanks in advance!

Got. You might post your request to Mathworks forums to ask if anybody has done this before.
