To calculate filter capacitor and inductor, you must know the ripple voltage and ripple current limits first. See the attached file. Can be helpful.

Many Thanx~~
Actually my concern is specifically for rectifier application. I want to know the effects of using secondary as Y or Delta with respect to rectifier? Like if I use secondary as Delta then from where I will use the reference for rectifier output side??

Hello;
What is difference between using delta/delta and delta/wye transformer for a 3 phase bridge rectifier?? which vector group is better and why??
I talked to a transformer manufacturer and he said use a delta/delta transformer in your circuit. But in that case I wonder from where the...
Hello experts;
Can Anybody plz elaborate the impact of transformer's vector group in bridge rectifier design??
Which vector group transformer is usually used for three phase bridge rectifier?? If I could find some document or sample, would be great.
Thnx and Regards~

I just need to calculate Inductor value in Henries under given ripple factor. Core selection, number of turns, etc is not my head ache. My question is how to calculate value of L for given ripple factor.
I studied about LC filters and how to calculate L and C values for given...
Oke thank you all..
Then how to select the DC choke value with other conditions like load voltage and current given. I know how to select parameters for LC filters. Is it same as designing LC filter components and then using only L and no capacitor???
Or there are some specific design rules...
Hello Folks!!
Is there any difference between DC choke and AC inductor??? I saw some rectifier with only choke filter. How the voltage is made ripple free then if there is no capacitor??
I read somewhere that recitfiers with DC choke filters need a very samll or even no capacitor. And the...
Hello experts;
I need to choose a transformer for a three phase bridge rectifier with 110Vdc and 50A average DC current at out put. Can anybody plz guide how to calculate transformer secondary voltage and current for this system. And also plz which configuration of transformer should be used. I...

Actually by design, I mean selection here. How to select.
I need to design a battery charger with above circuit. I did calculations for transformer selection. I need comments from experts, whether its oke or not??
Please see the attachment.
Thanx & regards~
Hello experts~~
I need to design 380Vac/110Vdc, 50A continuous DC current battery charger for Lead Acid batteries. First i want to select transformer for this system. Can anybody help how to design transformer for such system. It will be great If I could find some documents with details.
Thnx...
im new to this forum infact..I dnt know where to put this question exactly. I just realized that its Hobby Circuits and Small Projects forum :). Yes I need this much current.
Hi everyone;
I need to design a battery charger 380Vac/110Vdc. Charger should provide 150 A continuous DC current. First I want to select a transformer for this system. Can anybody plz guide how to select/design transformer for such application. It will be great if I could find some documents...
