Most of the design engineers I'm familiar with tend to be conservative. Your opinion is not that important. Opinions are like tailpipes, everyone has one, except for those like you who have theirs transposed with their induction system. FLNF TDD While I don't condone is attitude, he is absolutely correct. MHz switchers are common, have been in the field for years, and by the demands for miniaturization are getting more common all the time. If you don't believe me, pop open your PC, cell phone, PDA, etc and put a scope on one of the DC-DC converters. Also with many of these chips, the switching frequency is fixed and is not something the engineer has a choice of. The duty cycle varies to regulate the output. This is not something you'll find in the line operated power supply, but applications like CPU core voltage which may have to supply less than 2V at 50-80+ Amps (no, that's not a typo) from a 12V source where board space is a valuable commodity, or applications needing extreme miniaturization demand this sort of thing. Thanks, I just looked at the products available from: http://www.maxim-ic.com/ I've used their other products for years but I was not aware of their switching regulator chips. The original discussion concerned "SIMPLE" DC power supplies and some jerk chimed in calling everyone stupid, etc. Only because you (and DimBulb) *ARE* stupid, stupid. BTW stupid, you don't get much simpler than a (part of a) chip, inductor, capacitor, and two resistors. My experience has been with the switching power supplies in computers and test gear which is what I thought the discussion was about. Stupid, Sweet just said they're used in the core supplies of PCs. Though I suppose actually reading what people write is a bit beyond you. I've never seen one of those running at 1Mhz or more. A tiny regulator on a card or motherboard running at 1Mhz or more is something new to me. Heck, I learn something new everyday. Engage brain before mouth, stupid. Oh yea, I forgot, you talk out the other end. FLNF You _are_ always wrong, just like ALwaysWrong. Are you related, just lovers, or perhaps both? When are you going to call me a Nazi? You just intimated that I was a homosexual so go ahead, call me a Nazi. You're clearly a Demonicrat. That's your style, stupid. Oh man are you ever out in left field. You can't even spell your insults. Besides, Republicans disgust me but Democrats are special, they horrify me. Perhaps I should call you Dr. Sung who's nickname was "Often Wrong". FLNF TDD |

I'm assuming that running your design at a lower frequency would require less RFI shielding. I've seen some designs that put out so much noise that it interfered with everything else. TDD Our pot core transformers resonated very nicely at around 56kHz, and that was regardless of how the windings were configured. Did you have any RFI problems with your power supplies? Oh yea, don't let krw know about your pot core transformers, he/she/it will try to steal them and smoke them. FLNF TDD |

Hmm, that triggered a memory. I used to have an AC/DC one from the '60s - manual switch, and you could feed 12V DC in on the same power socket as AC. I doubt something like that would pass H+S these days, never mind the amount of people who'd try to feed it domestic AC with the switch on the DC setting and fry the thing That's actually a bit different. The AC/DC radios he refers to use a transformerless power supply with the tube heaters wired in series. For sure - it just stirred some braincells, that's all. The particular radio I remembered was an early (ish) transistor design - I think it may have been a Grundig, but I can't be certain now. The 12VDC ability was just to allow it to be run from a car battery whilst camping - I seem to recall my folks having a (black&white) TV that could run from a car battery, too, but I don't recall if it had a manual voltage switch like the radio did. Just struck me as interesting that it was (in theory) so easy to plug in to AC (via the same connector) with the voltage on the wrong setting and presumably cook the thing! The worst offenders for radios being plugged into the wrong voltage are 32V farm radios. The old 32VDC rural systems used the same plugs and receptacles as the 110VAC systems standard elsewhere, so it's common for someone unknowledgeable to plug a farm radio into a 120V receptacle and blow all the tube heaters. Well, I grew up in the UK, and it's been 240VAC as standard over there in just about forever (well, near enough, Google tells me 1916) - although I think some DC via private generation in big, isolated houses survived into the 1920's. The historical picture in the US is a lot more diverse, it seems (and more interesting because of it :-) cheers Jules |

I've had some extensive discussions with an EE friend over in Manchester and we're both learning something new all the time. I don't think I've ever asked if there were ever DC rural systems over there. These were off-grid and typically had a bank of lead-acid cells which were charged by gasoline or steam driven generators or windmills. There were 32V versions of virtually every small appliance of the day. Radios, fans, food mixers, etc. They made sense when farmhouses were often miles from the next house and more miles to the nearest town. |

And most farmers were quite happy to tie to the grid when it became possible - helping to build lines as well-- lots of rural electrification co-operatives came into being in the late 40's. My father was involved (from the utility side) with the the first one in Alberta, Canada, and the farmers were more than welcoming. The old windcharger/battery systems worked reasonably well for supplying lighting and small appliances but weren't capable of handling the heavier loads around the farms. -- Don Kelly cross out to reply |

Some had windchargers and some may have had generators but many were still without electricity of any sort. Windmills to pump water, kerosene lamps. and wood or coal for heating. The co-operative effort was to get connected to the grid at a time when there were few, if any, farms remote from towns that did have grid connections. This meant building a local distribution system and the utility providing the tie to the grid and operation of the system. The first case was in a tightly connected Mennonite "colony" and later ones were more general groups of farmers after the success of this one. In general rural (and urban) population densities were (and still are) lower than those in IL(about 1/10 the population in 5 times the area-admittedly mostly concentrated in the lower half (prairie/parkland)of the province ). -- Don Kelly cross out to reply |

Interesting - not seen those before.

But I've seen enough stuff that I know I haven't seen everything :-) :-) I'm sure there were all sorts of ways and means of extinguishing arcs, though - some of which may have worked better than others! It'd be interesting to know what larger power stations etc. did, too. Had some friends in NZ with a smaller plant (2,500 kVA) but I've not talked to them in quite a while, and I don't recall anything obviously resembling breakers on the site, although I assume they were there somewhere! cheers Jules |

The breakers were about the size of a lunchbox. Hi voltage AC breakers still do use compressed air in some. The 'blast' is aimed between the arcing contacts to literally blow out the arc. ------------- High voltage air blast breakers for AC have been around since the late 40's. They were/are modular with series sections and could then be extended to higher voltage by adding sections. The contact opening in a section was about 1 inch and 600psi air was driven through the arc, extending it towards a vent but not actually interrupting the arc until the arc naturally collapsed at current zero- then the arc products were blown out and the gap filled with good dielectric (high pressure air). A two gap section was good for 72KV and 2 of these in series for 161KV. Two gap sections could be linked together and put on longer columns at higher voltages there was a loud bang when they operated. The advantage of these breakers from Europe was that they were smaller, lighter, faster and cheaper than the oil breakers in use up to that time in North America. There was a bit of a war of words going on in IEEE PAS regarding the relative merits of bulk oil breakers and air blast breakers and air breakers won out. Even the old circuit breakers at, say 15KV up whether oil or air blast operated on the principle of removing arc products, replacing them with good dielectric, when the current went through zero. This principle is used for HV minimum oil and SF6 breakers (blast of oil or SF6 through the gap). Lower voltage DC (up to 350VDC) that we used on submarines just used blow-out coils to create a magnetic field that 'pushed' the arc-conducting gases up into chutes lined with alternating metal and insulating plates that would cool and stretch the arc. ------------ At lower AC voltages- say 5-15KV such breakers are often used- You could take one of these and derate it to about 400-500VDC and it would likely work. That current zero every half cycle makes a big difference. But I've seen enough stuff that I know I haven't seen everything :-) daestrom Me too -- Don Kelly cross out to reply |

Another variant that I worked with was spring to open and the bottom side of the mechanism pushed a plunger in a cylinder to make a 'gush' of air that was directed from below the contacts, up between them into the arc chute. Of course it was just a short burst of air, but the idea was to blow the hot gases up into the chute where the plates would separate and cool them. daestrom |
