Merge proposals November 2017

Reservoir capacitor → Rectifier#Rectifier smoothing filter

The following discussion is closed. Please do not modify it. Subsequent comments should be made in a new section.

Reservoir capacitor has been tagged to merge with the section of this article Rectifier#Rectifier smoothing filter. I am not the nominator, so my fan club can relax. However, there was no discussion section created for this proposed merge, so here it is. --Wtshymanski (talk) 20:04, 11 November 2017 (UTC)[reply]

Support - any unique content can be added here, no need for a separate article. --Wtshymanski (talk) 20:04, 11 November 2017 (UTC)[reply]
Support - A minor usage that certainly does not merit its own article, the minimal content could be merged to this article, Capacitor, or Power supply. --Chetvorno^TALK 21:35, 11 November 2017 (UTC)[reply]

The discussion above is closed. Please do not modify it. Subsequent comments should be made on the appropriate discussion page. No further edits should be made to this discussion.

This was sloppily proposed and executed, making this merge-action time-consuming to follow:

Proposal made by Sbalfour @ 04:07, 11 November 2017
Rectifier was not initially tagged for this. Version at time of proposal, last updated 10:12, 9 November 2017: there is no section header Rectifier smoothing filter in that version; indeed the term "rectifier smoothing filter" doesn't even appear
{{merge from|Reservoir capacitor}} was placed on Rectifier § Capacitor input filter at 21:37, 14 November 2017
Wtshymanski redirected and merged Reservoir capacitor to Rectifier § Rectifier smoothing filter @ 05:38, 20 November 2017, even though there was no such section header
Content was actually merged to the Rectifier output smoothing section
The lead sentence of the former article said: A reservoir capacitor is a capacitor that is used to smooth the pulsating DC from an AC rectifier.
The only usage of the term in the current Rectifier article is in the sentence "Transformer resistance modifies the reservoir capacitor waveform, changes the peak voltage, and introduces regulation issues."

So, the term reservoir capacitor is not defined now. wbm1058 (talk) 15:11, 21 May 2019 (UTC)[reply]

Oh, I see. It says "In its simplest form this can be just a capacitor (also called a filter, reservoir, or smoothing capacitor)". I missed that earlier. wbm1058 (talk) 23:54, 21 May 2019 (UTC)[reply]

The lead of Filter capacitor says: "Filter capacitors are not the same as reservoir capacitors, the tasks the two perform are different, albeit related." – i.e. different applications of capacitors. wbm1058 (talk) 00:18, 22 May 2019 (UTC)[reply]

This edit makes no sense to me: "The ~~reservoir~~ filter capacitor releases its stored energy during the part of the AC cycle when the AC source does not supply any power, that is, when the AC source changes its direction of flow of current." Common sense meanings of the words – a reservoir stores energy, not a filter. A filter separates undesired "B" from a mixture of "A" and "B" to give you the desired pure "A". wbm1058 (talk) 00:48, 22 May 2019 (UTC)[reply]

Filter capacitor → Rectifier#Rectifier output smoothing

There is clear consensus among the participants to merge, and the request has been very longstanding, so it's time to action it. However, participation was very limited, so post-close comments could conceivably change consensus. (non-admin closure) {{u|Sdkb}} ^talk 22:22, 23 August 2020 (UTC)[reply]

Filter capacitor has been tagged to merge with Rectifier#Rectifier output smoothing, with the nominator's comment "Unsourced junk article, along with Reservoir capacitor. I am not the nominator but I'm starting the discussion section which was not created when the article was tagged. --Wtshymanski (talk) 20:04, 11 November 2017 (UTC)[reply]

Support - very little non-redundant content to merge here, the rest of the article is just a list of capacitor applications which should be discussed at Capacitor. --Wtshymanski (talk) 20:04, 11 November 2017 (UTC)[reply]
Support - I agree with the above, should be merged into Capacitor. Should also be a little more about them in this article and Power supply. --Chetvorno^TALK 21:35, 11 November 2017 (UTC)[reply]

My view is that the Capacitor article is too large (at 99.8kb), and that a better target would therefore be a more specific article: Applications of capacitors. Klbrain (talk) 14:31, 4 April 2019 (UTC)[reply]

Agree, that would be better. --Chetvorno^TALK 21:07, 4 April 2019 (UTC)[reply]

Switched the templates to reflect this. Klbrain (talk) 08:37, 6 May 2019 (UTC)[reply]

I support merging into Applications of capacitors. A bit confusing that this discussion is here, though.--Theodore Kloba (☎) 19:19, 3 January 2020 (UTC)[reply]

Oppose This is tagged on the filter capacitor article as merge into applications of capacitors. I oppose both. We're WP:NOTPAPER, duplication and overlap just isn't a problem for us. Keep all of them. Andy Dingley (talk) 15:23, 16 December 2019 (UTC)[reply]

@Andy Dingley: I'm not sure why you're opposing the merge of an unreferenced article which duplicates the content of Applications of capacitors. As you know, there is an important distinction between what can be done, and what should be done, and the top 2 reasons for a merge are duplication and overlap. Given the content I therefore maintain my support for either merging to Applications of capacitors or simply deleting and redirecting the title to Rectifier.

Ripple (electrical)#Ripple voltage ⟶ Rectifier

Tag was placed at Rectifier § Rectifier output smoothing but no corresponding tag was placed at Ripple (electrical) § Ripple voltage. No discussion was started. – wbm1058 (talk) 02:29, 22 May 2019 (UTC)[reply]

I replaced the merge template with a hatnote. A bit annoyed at the merge-tag-bombing here, with no followup by the proposer. More care should be taken with merging technical content. wbm1058 (talk) 10:42, 22 May 2019 (UTC)[reply]

Filter and reservoir capacitors

@Matthiaspaul: You now have links to both reservoir capacitor and filter capacitor which go to different places. The article claims they are synonyms so there is no justification in having two different links (actually, we have three because there is the pre-existing smoothing capacitor. I would also challenge the notion that the term filter capacitor is applied to this capacitor. I agree that capacitor-input filter is a term, but that doesn't mean the capacitor is called a filter capacitor. The filter follows the reservoir capacitor, it is not part of it. I read the term to mean that the filter takes its input from the reservoir capacitor which is doing a somewhat different job to a traditional frequency filter. SpinningSpark 10:36, 19 June 2022 (UTC)[reply]

Yeah, I was wondering about this myself as well, but since someone added filter capacitor to the list, I didn't want to remove the term. If the term filter capacitor is (or was) actually used as a synonym to the other terms in RS we may need to disambiguate it to avoid the confusion.

The reason why I added those links was basically to "catch" their usage in the various articles and see if a common denominator can be derived to eventually change the redirects into articles properly defining them and crosslink to the other definitions to disambiguate them and let the subtle differences stand out better.

Personally, I wouldn't call it a filter capacitor (Filterkondensator) in this application either... Like you I would use the term only in conjunction with traditional frequency filters, but who knows...

In German, the output capacitor of a power supply is called a Glättungskondensator (lit. smoothing capacitor) or Siebkondensator (lit. sieve capacitor -> and sieving comes semantically quite close to filtering, so filter capacitor might not be improper use as well) when the focus is on the smoothing of the rectifier output or other variable-amplitude voltage source, neclecting a possibly variable load. However, if the focus is on the capacitor's use of short-term energy storage & supply it would be called a Pufferkondensator (lit. buffer capacitor) or, rarely and only for larger capacitors, a Reservoirkondensator (lit. reservoir capacitor). I see that in English the terms decoupling capacitor and bypass capacitor are used as well - whereas I would use those only when referring to the parallel capacitors located near the load (in German they would be called Stützkondensator).

"AC/DC adapter" listed at Redirects for discussion

An editor has identified a potential problem with the redirect AC/DC adapter and has thus listed it for discussion. This discussion will occur at Wikipedia:Redirects for discussion/Log/2022 December 9 § AC/DC adapter until a consensus is reached, and readers of this page are welcome to contribute to the discussion. fgnievinski (talk) 05:38, 9 December 2022 (UTC)[reply]
