If i understand you right well i thought that V1 and V2 should be ON and OFF at same time, and in opposite V44 and V3 should be ON and OFF at same time but inverted in compare of V1-V2, as the proper function of AFE rectifier. I read in theory i used that IGBT is best for AFE rectifiers thx to...
Hello, thanks for the reply,
i just want to ask about IGBT - you said i should try it without them only with diods, im not sure what means "Try maybe with only diodes first and IGBTs in the low side only."
Also i thought that theta =omega*t=2*3,14*50*0,002 thus its 6,28 (i take 2pif so...
I did what you suggest - make node for output on E3 and E3 (they was similar and got same problem) and it helps i can "run" simulation now, now i just cant get results duo to convergence problems :-D

well i get rid of some errors (obviously if i use hirearchical blocks i cant use PI regulator as name with "space" between PI and regulator) but now is there only problem in hirearchical block of PWM - nodes are floating....
here is curent version of my schematic
Moderator action: removed link...
I understand, i try to avoid inductor,
about that ground icon, i use one at input and i thought its enough, should i add ground also on output side and to regulatory part?
Could you suggest any N-mosfet instead parts i was using?
thank you wery much
edit: i actually got 2 grounds 1 on input...
Oh i know what you mean, i just think that theta (phase shift of voltage and current on input) is still 30 or 60 angle or 90 im not sure now (thats why i used constat for theta), also i didnt know how to get continuous measuring of that phase shift (theta), i was solving how to get "probe" to...
Well i followed mathematical desrcibe when i make this regulation schematics, if by sin generation you mean this SIN block then i have it there:
i followed this mathematic explanation for epsilon regulation:

I didnt have simulation schematics - i just simply try to simulate this scheme in post #1 just as it is (dunno if thats the correct attitude ? ) but i didnt find anwhere on internet someone simulating AFE controlers in OrCad.
Thanks for a reply BradtheRad,
i was trying to simulate single wave and 2 wave rectifiers and they were working,
active front end rectifiers can be bidirectional but this scheme is focused only in one way to get higher voltage on the output than on the input
To your last 2 points, my...
Hello, im trying to run this schematic :
with this regulation:
In OrCad 16.6 , i used PI regulator and PWM, but my simulation is making errors... and im unable to solve them. Can anyone pinpoint what am i doing wrong here? I ´m kinda self learning about these and i try to run some...
