Three phase thyristhor controled rectifier

Realy great implementation. A wise design you made cuz no errors and crashes occurs during rectifier operation and this program really can't handle fast switching circuits like this very well. .....ahhh one sugestion :-) lets we consider unrealistic abstract situation that ripple voltage is present at output of 0.2 kA rated 3 phase recti with choke input . U wil agree with me that at full rated output a filter capacitor even if he had whole 1 farad is only a strange useles curiosum ??? ....a very short lived and overpriced curiosum?? ;)

Thanks for your interest. I am not sure what you mean. Capacitors really decrease voltage ripples, but in some application no filter is needed like in dc-motor which armatoure has high inductance.

This simulation was working really bed without input AC inductances, the solver worked really slow when currents were switching between phases. Now, with three input chokes it works really nice.

yes thats true this program has problems when try to solve transient situations especially commutation points. when it approach such point a amount of calculus he need to calculate increase cuz commutation points are like black hole singularity ; whole things start gets compressed and some parameters achieve almost zero or almost infinite values. now a frame skipp mechanism go into action. Detect abnormal increase in calculus loops it need to solve in every time point to achieve values with acceptable precision. And after this a good algorithm should with zero problems decide where to stop approach to commutating point , approximate precisely values that with most great propability will appears on other side of commutation point using for this data he collect earlier. And warp himself to other side also. And if he strat this procedure too late we have permanent hang'o,freeze situation cuz he close too much to singularity and parameters achieve such abstract values that loops him in endless calculus madnes when he trying to approximate infinity. More if he decide too early to make jump than we have situation where after land on other side he has copletly inacurate to sitation data and circuit starts behave irrational and we have error on screen when he try to divide by zero or something like that. :-) Chokes smooth this situation cuz they cancel commutation points smoothing this time not a current but math stress to our processor doing so by makes variables less prone to any variation by adding inertia so values have limited field of change no mater how strong some other variables will try to change this state.

in power rectifiers for ripple reduction a phase multiplication technique is used. I

Was this circuit tested already in real?

Really nice...!!! Good job..!!!
