TMDSHVMTRPFCKIT: Conversion to TI per-unit.

Part Number: TMDSHVMTRPFCKIT

Hi All,

I want to control an asynchronous machine using the High Voltage Motor Control and PFC Developer's Kit  TMDSHVMTRPFCKIT.

My question is about the per unit conversion formula, how I could convert my simulation parameters (Ki, Kp, Umax, Umin, ... etc)  to the TI per unit  for all the projects in the controlSUITE?

// Initialize the PI module for speed
    
    pi_spd.Kp=_IQ(2.0);
	pi_spd.Ki=_IQ(T*SpeedLoopPrescaler/0.5);
	pi_spd.Umax =_IQ(0.95);
	pi_spd.Umin =_IQ(-0.95);
	
// Initialize the VHZ_PROF module
	vhz1.LowFreq = _IQ(0.2);
	vhz1.HighFreq = _IQ(0.5);
	vhz1.FreqMax = _IQ(1);
	vhz1.VoltMax = _IQ(0.95);
	vhz1.VoltMin = _IQ(0.2);

It is possible to use the TMS320F280049C or the TMS320F28377 with the TMDSHVMTRPFCKIT  Development Kit ?

Thanks in advance,

S.Tarik,

  • Hi,
    Kp and Ki values vary by the base current and base voltage of the target board. To move the parameters from one board to another, the scaling to use will be as follows:
    Kp2pu = Kp1pu * (Vbase1/Ibase1) * (Ibase2/Vbase2)
    Likewise for Ki also.

    Umax2pu = Umax1pu*Vbase1/Vbase2
    Likewise for Umin

    The control card for x049c is 120pin HSEC connector based that will not fit into the HVMTRPFC kit, and it will need an adaptor, which I dont think we provide. Will confirm soon.

    Thank you Sir,

    I just wanted to confirm that we don't provide the adapter as I mentioned yday..

    Hey, correction
    Look at this link for the adapter

    Ramesh,

    Thank you for taking into consideration my request, I really appreciate the work you have done for us, it was a good news for us!

    I am looking for  the same control motor projects already done on F28035, F28335 in the ti/controlSUITE using the  TMDSHVMTRPFCKIT but for the F280049C and F28377D? Could you tell me please where I could find them?

    Thank you in advance,

    Regards,

    S.Tarik,

    No, we don't have any. Basically they are portable and will be an exercise for the user.
    I am closing the thread with the assumption that the issue is resolved. If you have anything else to discuss related to the same topic, you can reopen the thread by continuing to post within 30 days.

    Hi Ramesh,

    Does TI provide the pinout file for this adapter, we ordered the adaptor but we don't receive the pinout pdf file description,

    Thank you,
    S.Tarik,

    S.Tarik,

    Almost all of C2000's board schematics are provided in C2000Ware. We also include a mapping of each controlCARD through the adapter.
