Re: "Reliable sources needed"

Good day Wtshymanski. You left a comment on my talk page. I've replied at Talk:Maglite#Thermal management article section. With kind regards, --Unforgettableid (talk) 01:02, 24 January 2013 (UTC)

Buck-Boost transformer Frequency?

I saw your edit on this page regarding frequency. This paragraph confuses me and I would like to make the English clearer.

All transformers operate only with alternating current. Transformers change only voltage, not frequency. Equipment that uses synchronous motors will operate at a different speed if operated at other than the design frequency. Some equipment is marked on its nameplate to run at either 50 Hz or 60 Hz, and would need only the voltage adjusted with a buck–boost transformer.

How do you understand the intended meaning of this paragraph?

• that incorrect application of frequency (50/60) can be compensated for by voltage?
• that buck-boost transf. cannot compensate for wrong frequency?
• a confused paragraph (maybe unrelated) and could be removed from the article?

After you replaced some text, I am stumped on it's meaning intent and would like your input. Ideas? Thanks 174.118.142.187 (talk) 05:30, 24 January 2013 (UTC)

I don't see the problem. It says that transformers can't change frequency. Some equipment is lablelled "50/60 Hz" and only needs the voltage changed to work. What's unclear? --Wtshymanski (talk) 14:11, 24 January 2013 (UTC)

For one thing: What are frequency comments doing in a transformer article?

"Some equipment is marked on its nameplate to run at either 50 Hz or 60 Hz, and would need only the voltage adjusted with a buck–boost transformer."

Doesn't that sound like nonsense? Another editor has attempted a smooth-over also but I still don't like it, yet. I didn't want to remove or edit it unless I understood what you felt it was supposed to be doing in this article. Thanks. 174.118.142.187 (talk) 03:39, 25 January 2013 (UTC)

Given that some equipment IS so marked, and needs only the voltage adjusted, it clearly is not nonsense. Why do you think it is nonsense?

For example - I have an AC power adapter for a small travel radio. It uses a linear power supply and so can work only from 120V nominal, not 220 as in Europe. But it doesn't care a whit about the incoming line frequency.

Where do you get the notion that a frequency mismatch is somehow "compensated for" by a voltage adjustment? Or that the text is making any such claim? Sorry but THAT sounds like nonsense.

Yes, the text says that a buck-boost transformer cannot compensate for wrong frequency. It says pretty much that exactly, in fact.

I don't see the problem here either.... Jeh (talk) 05:29, 25 January 2013 (UTC)

I was thinking about pointing out that Wtshymanski is right -- again -- but he seems to not like it when I do that. I figure that it is a combination of his natural modesty and humility and his aversion to any sort of conflict. :) --Guy Macon (talk) 06:11, 25 January 2013 (UTC)

Yeah, keep kicking me some more as it is starting to make sense. :) I guess the wording still feels a little off to express this sentiment. To add to yours, WSMS is a little different in his approach but his edits are based on some knowledge and this should get him to clean his page real quick!
