    Great explanation. The circulating current on the primary side of DAB and the circulation current on the secondary side of the DAB needs more explanation? In a single circle, can you mention the transition between switches in regard to circulating current through the diode due to capacitor discharge?

    • @bhuvaneswarigsfreeonlineco4109
      @bhuvaneswarigsfreeonlineco4109 4 หลายเดือนก่อน

      If you are sensing three-phase currents, then to convert them into d-q, you will need these transformations. these d-q currents are used in flux and torque calculations.

    Madam , can you please share your email id.

  • @awan2344
    @awan2344 4 หลายเดือนก่อน

    And one more thing. You have mentioned that when we have the speed reference, then you have created a block in red colour just above the speed controller & said that when speed ref we have , the flux estimation can be done. My point of view is that when we have the speed ref, then our drive will calculate the output frequency . Because freq is directly related to speed. However in order the constant V/f ratio, the drive shall choose the right voltage value to be send to output. Then when drive will decide the output voltage ( based on frequency) the stator flux will automatically be set at certain value . Am i right ?

    • @bhuvaneswarigsfreeonlineco4109
      @bhuvaneswarigsfreeonlineco4109 4 หลายเดือนก่อน

      In most of the cases, especially in induction motor drive, we will set the flux at rated value as long as the reference speed is below base speed. For operating above base speed, flux weakening is employed where the reference flux is set at a lower value than the rated flux. (Flux above based speed=rated flux*rated speed/new reference speed) Voltage is automatically decided based on flux error, torque error and voltage vector selection table.

  • @awan2344
    @awan2344 4 หลายเดือนก่อน

    Madam, in implementation phase , ypu have shown 2 speeds signals. 1 signal which is setpoint at which we want to run motor. Second signal coming from motor feed back which is actual speed. But in DTC there is no feed back sensor mounted on motor which measures the actual speed.

    • @bhuvaneswarigsfreeonlineco4109
      @bhuvaneswarigsfreeonlineco4109 4 หลายเดือนก่อน

      From the three-phase currents that are sensed, torque can be calculated. Synchronous speed can be inferred from d(flux angle)/dt. With the calculated torque vale and synchronous speed, actual rotor speed can be deduced. No mechanical speed sensor needed.

    • @bhuvaneswarigsfreeonlineco4109
      @bhuvaneswarigsfreeonlineco4109 หลายเดือนก่อน

      If you know the equation for the current waveform, all you need to do is to calculate integral of [i^2 dt] and divide by T and take square root. That will give you RMS value. We know the current expressions here. So, it should be doable.
