Q:I would like to use this circuit to power arrays of high power LED'sI understand the properties required to power LED'sI have beginners knowledge in electric circuits and have done some research on this circuit. I have come across several posts stating it is dangerous to connect this circuit straight to mains power. I don't understand is what makes it is so dangerous?AndIf possible, how can it be made safe without using a transformer.
The neutral leg of the AC (assume the bottom on the diagram) is grounded to earth ground at the house service entrance and also at the center tap of the power pole transformer (in the US). If your project box was metal, and you had the 0 volt output attached to the metal case and happened to touch earth ground through you. You would get shocked since during the negative half cycle, positive voltage would go through ground, then you, the metal box, through D4, back to the AC hot (on the negative half cycle). Ouch! Always use an isolation transformer or any transformer where the secondary is not in any way tied to the primary. That way you can ground either dc lead from the rectifier to ground and not have to worry about electrocution.
Q:Actually both amplifies the input voltage. A step up transformer amplifies the input voltage and a transistor also amplifies. So what is the differece????
Transistor Transformer
Q:Is the upper oil temperature of the transformer high or lower?
Of course, is the upper high, thermocouple generally installed in the top.
Q:What is the meaning of the high voltage side and the low side of the transformer?
Under normal circumstances the role of the transformer is to high-voltage transmission (saving material to reduce the loss) over the power to reduce the voltage (there are boost in the power plant substation) to meet the conventional use of electrical equipment standards. Therefore, in the conventional step-down transformer input (also called once) is the high-pressure side, the output (also called the second) is the low side.
Q:A transformer has a 100-turn primary coil and 1000-turn secondary coil. The primary is connected to a 120-V AC source and the secondary os connected to an electrical devic with a resistance of 1000 ohms.what will the voltage output of the secondary be?what current flows in the secondary circuit?what is the power in the seconday coil?what is the power in the primary coil ?what is the current drawn by the primary coil?
The ratio of teh secondary to primary turns gives you the voltage multiplication on the secondary. Thus N 1000/100 10 So the secondary voltage is Vs Vp*N 120V *10 1200V The secondary current Is Vs/Rs 1200V/1000 Ohms 1.2 A Power in secondary Ps Vs*Is 1440 W Power in Primary has to be the same as secondary (or less due to losses) 1440 W Ip Pp/Vp 1440/120 12 Amps
Q:I'm a beginner in electronics ,I have a big , old transformer (I think it is AC) , only supplies + current. (36 Volts)I also need - current to drive an amplifier.So i think it's an AC to DC converter i need. (It's just a guess , i don't really know.)How can i achieve this ?Note : If you need additional details , please include how i can get that detail , just in case i don't know.
A transformer with the correct secondary voltage can be used to make a DC power supply. Just put a full wave bridge and a filter on the output of the transformer.
Q:anyone else see the trailor for this movielooks kinda goodthough, it may be were the transformers are bad guys, i dunno
Ehhhh I'm not sold on the concept yet. I want to see a real finished transformer first. I'm sure they'll get the transforming part right, but the sound I think will be wrong and stupid, and they'll probably look like those robots from Sky Captain
Q:if the transformer converts 240v ac to 8V ac, ratio 30:1 then it should step up the voltage by the same ratio, i.e, 15V ac to 450v ac.but it's not the case !!
It will, but you have to realize that the series resistance of the primary (which is now your secondary) is getting in the way. I am going to guess that this is a very small transformer, capable of one or two VA at most. The rating is a little tricky too. A 240V-8V transformer puts out a significantly higher voltage, maybe 20-30V, with no load. It's rated at 15V because under a load, with magnetic and resistance losses, the effective turns ratio is lower. Used in reverse, the opposite problem exists, because your actual turns ratio is much higher than 30:1. Edit: If it wasn't for silly ideas a lot of inventions wouldn't have been made. The secondary probably doesn't have enough turns to provide adequate self-inductance at 240 volts. It would just act like a short and burn out. There is also a possibility that there is not enough dielectric strength between adjacent windings or the frame to prevent arcing, but most transformers are designed to withstand thousands of volts so this is less likely. If possible, I'd recommend trying lower voltages (perhaps 8V from another transformer), and measuring the current with the primary (now the secondary) open. Put a load resistor in there to start just in case. If you're drawing more than a few milliamps, don't try hooking it up to the mains.
Q:I'm a good Transformers fan, but i've only really watched the more recent shows like armada, energon, etc. so i'm confused with some things in the new movie:1. Is Jetfire really supposed to be that old?2. Jetfire mentioned the Optimus must be the last decendent of the Primes? is Omega Prime one or no?3. When the Fallen appeared in the comic where he first showed up, did he have the same power over Megatron4. Did anyone else notice that Ratchet just showed up during the forest battle scene?5. Did Megatron transform into both the cybertronian tank and plane in the movie?6. Anyone else find the Twins insainly rascist?7. Is Wheelie supposed to be a small toy in the universe?8. Is the human changing robot really in the series or just the movie?9. Can Constructicons really morph with each other to make a giant?10. Is Starscream the one that eventually switches to the Autobots?11. Does the Decepticon attaching itself to the sattlelite have a name?Thank You for clearing things up
1. No Jetfire isn't that old. although his age might be a little higher than others. 2. Omega Prime is a fusion of Optimus Prime and Ultra Magnus. So technically the answer is yes and no because it's actually Optimus Prime fused with another transformer. 6. Not really. It was just extremely stereotypical and a little annoying. But if you think that all stereotypical representations in movies are racist, then you'll have a problem watching any movie. Take asian stereotypes for example. 8. Pretenders (what the human changing robot is called) were first conceived in 1988, I think by Marvel Comics not sure about that. And yes it was in the Marvel Comics production of Transformers cartoons. 9. Yes, in the cartoon series they were able to merge into a larger Transformer called Devastator. 10. No, Starscream always tried to take control of the Decepticons behind Megatron's back or when Megatron is injured (eventually he is killed by Megatron-turned Galvatron). Jetfire is the Transformer that switched sides from the Decepticons to the Autobots. 11. The Decepticon's name is Soundwave.
Q:How does a step down transformer decrease the output voltage but increases the output current? And how does the step up transformer does the opposite thing?
that one you have to ask the energy saver I think they have the solution.
