    I never thought of the dead band. thank you for the info. I'm going to design the 3phase inverter which also can be used to control the single phase motor for the trainer purposed. But I have a problem in doing the programming. I need to learn the arduino which looks more easy

    • @RAJANVAMJA
      @RAJANVAMJA 6 ปีที่แล้ว +1

      the speed of calculation is more important for making V/F control precisely.
      so please go for high speed controller in Arduino environment itself.

    Nice job. You may need a p-channel mosfet after the igbt to prevent reverse current damage. As the washer powers through the agitation, it'll encounter a ton of reverse flux.

    Hello bro. Congratulations for your good job. I wanted to ask you some question . What the number of the IGBT are you using?? And also let me ask you the second question. That IGBT booster you build can it be controlled by Dc 400?? Hopefully to hear from you, thank you

    • @RAJANVAMJA
      @RAJANVAMJA 7 ปีที่แล้ว +1

      yes, it can be used with 400V dc but I suggest you to go up to 350V dc link with the IR2110 driver IC. if you want to go still higher than need a different type of driver circuit. whatever we have tried that was manually soldered. so giving higher voltage can lead to burning of the device or driver.

    • @RAJANVAMJA
      @RAJANVAMJA 6 ปีที่แล้ว

      yes.. it is quite possible.
      you can use ADC channel to give input of modulation index (which is proportional with voltage and frequency ).
      you can use VARIAC NOBE to change it.
      that is also available in our circuit.
      you can see in video at 7:46 time . parrallel to switch one nobe is connected. we can use it when we want analog control of drive.

      you can design deadband circuit using NAND gate, registor and capacitor..
      AS Shown in OUR VIDEO AT 5:43 time.
      or
      recently advanced controller have PWM TIMER-> This type of timer are PROVIDING advance compare operation and can generate COMPLIMENTED PWM PULSE with predefined DEAD BAND TIME.
      WE have utilized the PWM TIMER FROM controller STM32F407vg.

      i have 1 mS dead time delay with my circuit (1 mS generate by RC time constant, R=10Kohm and C=0.1 uF then we have delay = 10.000 x (0.1x10^-6) = 0.001 = 1mS), what happent if i put this pulse for three phase inverter using 180 degree conduction mode.... ? it's work or not ?

    • @efrykaliky7363
      @efrykaliky7363 6 ปีที่แล้ว +1

      if ill use 1 uS for deadtime delay, i can't see the difference of PWM signal (S1 and S4). i have 1 uS with R=10 ohm and C=0.1 uF, then we have delay for deadtime is = 10 x (0.1s10^-6) = 0.000001 = 1 uS.

    • @RAJANVAMJA
      @RAJANVAMJA 6 ปีที่แล้ว

      actully we using SPWM for GENERATING output voltage.
      where switching frequency is 5kHZ. so it is having very small switching time. so i requied 1 us dead band.
      if you are puting higher dead band. it will reduce your output voltage.
      no other complication .
      you have to compromise with output voltage reduction

    • @RAJANVAMJA
      @RAJANVAMJA 6 ปีที่แล้ว +1

      yes it will work.
      but your output votlage will reduce considerably.
      because if your output voltage having frq. 50 hz than ur SQUAREWAVE will have 20ms time period.
      so ur output votlage will reduces by (2/20 times.)....!!! :)

I apologise for this lonnnng comment ☺ and thanks a lot for sharing your project with us .

      already we are helping person name;;y @KUSHAL N ... Who has commented like you and dedicated to do V/F CONTROL.
      actully your method to make lookup table is ancient. now in the market to fast controller are avalable with high proccesing speed. which can calculate sine in infraction of the microsecond.
      so i suggest you to go for STM32F407VG.
      now a days , STM32 is possible to program using directly from matlab simulink simillar like DSPACE2210(you may have heard name- it is consting 5lac rs aprox) . stm is cheap and quite affordable.
      till date we have done . 1)all chopper control 2) spwm , svm , (Thi open loop) 3) scallar closed loop control.
      4) advance control : DTC AND FOC FOR INDUCTION MOTOR .. as well as PMSM AND BLDC.
      so better to shift to STM32F407vg.
