For higher power applications, and solid state converters, I recommend Lamda products.

Antec, there is NO substitute! 300 watts is no where near enough, jump up to 400-500 watts, this is what I'm using and it is VERY reasonable. I bought it at http://newegg.com\n\nhttp://www.antec.com/us/productDetails.php?ProdID=26500

Its hard to explain in detail without knowing what type of output you specify. An inverter takes a specified DC input voltage and changes it to a square wave, or semi-sinewave output which can be used to power equipment designed to operate from AC output current. The circuitry and components,as well as complexity and cost of the designs vary greatly and are dependent upon the desired output power and desired output waveform. Some sensitive equipment can only operate from a true 60Hz sinewave, and inverters designed to provide such an output are more complex, and therefore more expensive. Any more detail would require you to know basic electronics, check out inverters: schematic diagrams in your browser.

Here is an idea.\nCompare power supplies by weight, volume and power density using various batteries.\n\nThere are many batteries on the market now, so it might be very educational for you and anyone looking at your project.\n\nConsider using the following batteries:\nLead acid battery\nLithium-ion battery\nLithium ion polymer battery\nNickel-cadmium battery\nNickel metal hydride battery\nMolten salt battery\nSilver-oxide battery\nWater-activated batteries used in radiosondes\n\nYou could compare different AA batteries of different types and costs.\n\nA good starting point for references on batteries is on Wikipedia:\nhttp://en.wikipedia.org/wiki/Batteries\n\nYou might even be able to get a small prototype fuel cell if you ask to work with a battery manufacturer, a research company, or someone like NASA.\n\nYou should start thinking of what kind of a hypothesis you could write to kick of the experiment.  Hint: Don't worry if your experiment fails and you fail to prove your hypothesis. Sometimes the best experiments are failures!\n\nHope this helps!

Yupp... but unfortunately is a hardcopy on my desk. Perhaps you may straight to tell us what\n\n1. You are designing from HT to Transformer 11kV / 415V\n2. You are designinig from Transformer to LV ??\n3. What is the kVA of the transfomer?

Here are some sites that may help.  Both have circuit examples utilizing LVDT's.  Hope this helps.

PV tech is expensive and only works when the sun is shining. Not the best solution when we have a delivery infrastructure for bulk power. Don't forget about all the batteries a solar set-up needs. Where do they go when they no longer hold a charge?\n\nNuclear is the best solution.

Go to the APC site and enter your exact configuration and they their site will tell you exactly what you need to order. \n\nI ran your approximate configuration and got this answer\nAPC Smart-UPS XL 2200VA 120V + (2)SU48XLBP Battery Unit\n$1900 as the best option. They also had a less expensive recommendation. But you need to run the configuration yourself, because you did not provide all of the information that is needed to configure the UPS.\nBut you

I can't really call them suppliers as they develope their own techniques and then use them. They don't supply the technology to anyone else.  \n\nThe best known companies are Iogen Corporation,Genencor, Novozymes, and Dyadic International, Inc. There are a handful of other companies. \n\nTo the best of my knowledge there are only a handful of production plants either running or in development.

In the USA, a good reference for suppliers is the Thomas Register, online at:\nhttp://www.thomasnet.com/\n\nSearch for manufacturers who use your products in their end products (e.g. search for machine tool manufacturers since they use washers, brackets, etc.)\n\nHope this helps!

Yes it is. The best way to get answers is go to a site like newegg.com  The site is one of the best- they give very detailed information about the many options that are available for making purchases. Most vendors are rated for reliability, speed of delivery, handling of customer problems, returns policies, guarantees, etc. Its good to familiarize yourself with the ratings before buying .

I have a client who is selling computer accessories through these folks: www.motherboardllc.com.  So far he seems very happy with their customer service.

As far as I am concerned, alternate suppliers have to prove that they have the know-how to continue to supply the lowest price electricity over the long term.  In my area, power prices are set by auction contracts.  My electricity supplier must be a "player" in the market with a good track record.  All of the other stuff is just fluff.  Show me the lowest $/kwh rate and lock it in for a decent length of time or go try selling used cars or something.
