Naki hocam merhaba, yine ben :D burada faz açısını kontrol ediyoruz ya bu neyin faz açısı oluyor, referans sinyalin açısı mı oluyor. Hocam bir de bu faz kayması kontrol yöntemi olarak mı geçiyor.

[@nakiguler]

Merhaba Berk, evet referans sinyalin faz açısı oluyor. Burada kontrolden ziyade faz açısı ve modülasyon indeksinin etkisini göstermek istemiştim. O yüzden feedback almadan yaptım.

Hello Sir, how can I select the values of the filter inductors and capacitors? Would you kindly suggest a text or tutorial please?

[@Abul.Munjer]

sir, i have designed a simulink model of MMC for capacitor voltage balancing . when i connect it to the grid as you uploaded, before connecting it works as natural multilevel converter, load current was same but after connecting it to grid, converter takes huge current from the grid. what may be the possible causes for that? thanks in advance.

My grid and inverter current waveform are almost 180 shifted . What could be the issue ?

[@nakiguler]

It's possible because when you transfer to power from inverter to grid, it should have a phase angle. Actually, it shows, your system transfer the current without reactive. Current direction should be opposite. It's normal.

Sir, after setting phase shift 2 when I close or set 1 to parrele swich than I am not getting Igrid and Iref waveform as its your ......however before this operation everything is as you are getting? what could be the possible reasons?. and what is to be set sample time at scope: -1 is by default I am using Matlab2018a

[@nakiguler]

If you select the phase shift as 2, the inverter voltage may not synchronize to the grid. Please check the Matlab function block codes. Did you convert degree to rad/s? If you select the sampling time as "-1", it will be equal to the base sampling time of simulation.

[@hocho7254]

@@nakiguler Thank you sir, identified and fixed the issue. However, for synchronisation it is necessary to have same phase of Vgrid,Vinv ,Iinv and Igrid ???

[@narasimhaprasadtulasi7539]

by changing phase angle ,current phase is adjusting when parallel switch is zero ,but when we make parallel as 1 ,currents ig and i_inv both are looking like staircase ramp signals increasing in opposite directions continuously ,but if i put phase angle as zero, even in parallel 1 state(after conn grid) i am getting waveform magnitudes of grid load inv as you said at last in video please help me where i made mistake sir.
