how to Decelerate motor correctly?
Dear Yanming Luo
As you know we have "gMotorVars.VdcBus_kV " to get the DC bus voltage ,so Do we have any variable for total Current to see the motor current ?
thanks for attention

In reply to Dave Hunson:
I got a bit confuse ..
i thought the current vector is equal with the dc_bus current ,isn't it ?Why?
I would be happy if you explain about it.
I think what I need is DC Bus current .
Happy new year !
1.my question is simple ,and that is would it be possible to get DC current bus from any variable (sort of like VDC bus which is in gMotorvar) if so,which one?
2. the other way would be to get it from Ifb_Sum (and write my own code for it),is that right ?
Thanks for attention .
Happy new year!
I think I realized about
take a look at this picture which has 2 leg shunt resistor .
Ia,Ib,Ic is the value of the current when PWM is ON which turned in to Id and Iq
in short, TotalCurrent is the amount of current which pass from IGBT/Mosfet Module when PWM is ON .Is that right?
in addition ,this current TotalCurrent =sqrt((gMotorVars.Id_A*gMotorVars.Id_A)+(gMotorVars.Iq_A*gMotorVars.Iq_A));
is like a pulse and depends on PWM carrier freq (15khz) we can not say this is the DC Current bus .am I right?
I would be happy if you answer these 2 questions .
Thanks for attention.
