help me the circuit diagram of 1 MHz  work with  3V.  0.5 to 1.5 w.?

You can use an integrated circuit, like LTC6906 from Linear Technology which goes up to 1MHz at 2.25 - 5VDC supply,\nsee:  http://www.linear.com/pc/downloadDocument.do?navId=H0,C1,C1010,C1096,P9790,D6998\nAlternative: MAX5094A by Maxim,  see:  http://www.maxim-ic.com/quick_view2.cfm/qv_pk/5017\nI didn't have the time to check the output power, but if it's not enough, a simple emitter stage transistor will do.

Do you think those would help?\n\nhttp://scholar.google.com/scholar?q=design%20of%20a%20Lithium%20Niobate%20modulator%2040%20gbps&num=20&hl=en&lr=&safe=off&rls=GGLR,GGLR:2005-38,GGLR:en&oi=scholart

I've found a good site introducing and explaining the voltage and phase relationships between delta and wye 3 phase transformers. Try www.elec-toolbox.com/usefulinfo/xfmr-3ph.htm\nI hope that this proves useful for your research.

If this is 230 V circuit\n\nwatts = 4600 w\n\nIf this is 110 V circuit\n\nwatts = 2200 w

Bah! I thought it was AMD based on the voltage alone...\nchecking Intel now...\n\nBased on every 3.4GHz CPU I could find on Intel's website, your voltage is within range. Intel specifies an operating range of 1.25-1.40v for most, and up to 1.525v for some.

dont forget the formula I= R/U\nsort them and u will get the answer\n\n Current: 625mA (milli amperes)\nResistance: 19.2 ohms

go to radioshack...they sell basic instruction manuals, circuits and all the bits you'll need

If there are 3 capacitors, Ca, Cb, Cc then use the following:\n\nSeries\nTotal Capacitance = 1 / (1/Ca + 1/Cb + 1/Cc)\n\nParalel\nTotal Capacitance = Ca + Cb + Cc

This is not complicated at all.\n\nLM317 is an IC device with only 3 terminals.  Here's an URL to the diagram:\n\nhttp://www.national.com/pf/LM/LM317.html\n\nYou willneed a transformer, full bridge rectification circuit, and filters.   You need to spec the transformer so that the output of the rectifier/filter is at 15V DC at full load.  Notice that under no load, the ouput will be at sqrt(2) * (ac voltage).  Under full load, it should drop to the RMS value of the outout.  (basically means to use the 15V transformer)\n\nThe filter capacitor must be large enough so that ripple will be at minimum at the full load.  4700microF or larger should be sufficient.\n\nRemember to heat-sink the 317, as it will get quite warm at full load.

Divide by the voltage and multiply by 1000.\n\nIf you are working with 3 phase power, divide again by sqrt(3)

What voltage dc, or do you need to be able to vary it?  What current capacity do you need?  What ripple voltage is acceptable?

Not the easiest thing to explain via email but the best way to start is to understand clearly the function of the symbols shown in diagram. Once you understand what each item does find a starting point - usually the power supply and walk through it. ANother way is to get the corresponding termination diagram. I find them much easier to understand.

less than 0.3  for power sations\n0.5ohm for substation\n1 to 2 for homes

Probably nothing as long as the voltage is correct. I wonder -- how do you know you have 50hz?
