I just read about buck converters and boost converters and buck/boost converters. Great stuff.
But, why is a step-down converter called a buck converter?
I tried to research this myself. According to Google Book search, the phrase buck-boost transformer was in use at least as early at 1891 in a periodical called Architectural Review.

I suspect the term as applied in electric systems may have been created originally for transformers -- more specifically for autotransformers -- and relates to an idea that was commonly known back in the day. Logs were bucked (either under- or over- bucked) depending on from which end of the log sections were cut for milling. (Starting at the thicker base and working up or starting at the top and working down.) A bucking transformer can be seen as doing just that. And I suspect that's where the first author of the term got the idea since logging was a commonly shared experience in the 1800s.

It's the same sense as to "buck" a trend:
- to oppose or resist (something that seems oppressive or inevitable).
"the shares bucked the market trend"
synonyms: resist, oppose, contradict, defy, fight (against), go against, kick against
"it takes guts to buck the system"
So you're "bucking" the input voltage to reduce the output voltage.

Buck regulators use an inductor which opposes the current flow when the switch opens. So it's just as valid as the transformer use.

I may be wrong(apparently there is no way to qualify any answer here as correct), but I had always assumed that "buck" referred to an action similar to a "bucking bronco or bull". A buck converter sends a voltage pulse only as often as it needs to in order to provide the rectified and filtered DC output required, just as a "bucking bronco or bull" will "buck" as often as he feels he needs to in order to eject the rider or loosen the strap.

Since most of the switching topologies work by making controlled pulses in response to operating conditions, it's hard to imagine that we'd take the "bucking" notion and specifically put it on the one that's a step-down.

@gbarry - I sort of see it in the opposite scenario. An animal "bucks" as high and often as it need to in order to obtain it's goal, I see it as "providing action only to the extent that is required", rather than the dictionary version, which implies more of a "resistance" or "opposition" aspect, and would seem more analogous to the implementation in a linear regulator...

@gbarry - I sort of see it in the opposite scenario. An animal "bucks" as high and often as it need to in order to obtain it's goal, I see it as "providing action only to the extent that is required", rather than the dictionary version, which implies more of a "resistance" or "opposition" aspect, and would seem more analogous to the implementation in a linear regulator...

I suspect the term as applied in electric systems may have been created originally for transformers -- more specifically for autotransformers -- and relates to an idea that was commonly known back in the day. Logs were bucked (either under- or over- bucked) depending on from which end of the log sections were cut for milling. (Starting at the thicker base and working up or starting at the top and working down.) A bucking transformer can be seen as doing just that. And I suspect that's where the first author of the term got the idea since logging was a commonly shared experience in the 1800s.
