    Hello! Thanks for the video, it was very informative! At 2:55, I did not understand the factors 8.69 and 1.414 that do not match with any value in the formula in the middle row. Request you to explain it in some detail please!

    • @TechSimulator

      8.69 is 2000/230. That is output power/ output voltage. 1.414 is root(2) to find the peak value

    One thing not clear is D(wt) = Ma*sin(wt). How could D be negative. Shouldn't it be D(wt) = (1+Ma*sin(wt))/2 ?
    Also, the LC filter values were chosen w/o taking the load value (R) into account. In the simulation you chose 100 Ohms. What if the load changes? How would you control the damping ration of the LPF? On command or load change you may get oscillations and instability.

      @aquilrodrigues8155 4 года назад +5

      its simple
      first calculate the current for given load,
      i= Power (2kw given)/ V(230v) = 8.69A
      next he has multiplied by 1.414 which is nothing but root(2) to get peak current
      and finally he has taken ripple percentage as 20% hence multiplying by 0.2

      i am considering a 2Kva inverter. So for a single phase 230V RMS voltage, the maximum current would be 2000/230 = 8.69. this is value is in rms. so we need to take peak value of it. so we multiply this value with root 2, that is 1.414.
