Current Sensing

1

Hi,

I am working on Matlab for programing my stm32f429 board. I am trying to make control algorithm for clarke transform, clarke to park, park to clarke, inverse park. Simplefoc shield look like has two current sense output. Don’t we need three for clarke transform.

If they are not ia, ib, ic what are the can they be id, iq currents?

As far as I know you can calculate the third one from the 2 you have. But simplefoc also support’s 3 current Sensors.

Yes i can calculate so are pinouts (ia, ib, ic) phase currents?

You only need two, the third one can be calculated by kirschoffs current law.
