Once a transformer is designed, engineers build a prototype and then measure the losses using open circuit and short circuit tests. The objective of a good design is to reduce the losses in the transformer. There are 2 main kinds of losses in a transformer that are useful for engineers. The smallest transformers used in RF industry is of the order of few cubic centimeters and high power transformers used to interconnect power grids can be in the order of few cubic meters and can weight several tons. Transformers are also used in electronic and RF industry and hence they vary in size. Since the adoption of AC power, transformers have become ubiquitous in electrical power transmission and distribution industry. In electric power applications, transformers are used to increase or decrease the AC voltage. Try to stick with out-of-the-box solution (if this is an option for you/do not intentionally want to make it harder as it could be).Applications of transformersTransformers find useful application in electric power industry. Make sure that you got all the basics before trying to solve a problem by throwing more stuff unto it. TL DR Do not tamper with mains electricity voltages if you do not know what you are up to. That is the reason why your design will mostlikely have the size of a shoes box while there are adapters out providing multiple usb ports with 5V/5A in size of an arduino. There the AC is first rectified then chopped with a high frequency, transformed via a much small transformer and then rectified again (for details search for Switched-mode power supply). Modern AC/DC converter (like the little power grid to USB thingy) actually use a far more advanced approach. But again: only do it if you know what you are dealing with. A source describing some parameters and formular for such an effort is. But one has to make sure that the number of turns on the primary side is not to low (to avoid heating due to high currents) or to high (low maximum power transfer). The ratio is for the transformer is actually computed via the formular N1/N2 as you figured it out. Considering the numbers you gave there any supply abled to supply 5V with a current rating greater than 3+1A should be fine to power your RPI and arduino in parallel. Which means as long as the (maximum allowed) current rating of your supply is greater than the drawn current your will be fine. Additionally the supply need to be potent enough to provide at least the maximum current required by your devices. Generelly speaking one has to make sure that a (voltage) supply give the right level of voltage (in your case 5V). In the worst case you or somebody else might get severely hurt!įurthermore your comment "Can If we convert 230V AC to Directly 5V 3A DC and supply it to Raspberry PI and then take this 5V 3A DC and Convert it to 5V 1A DC and Supply it to Arduino" is an indication of a missconcept regarding voltages and currents: Actually you should not touch main power supply at all if you have not a very good idea what is going on at those voltage levels. I strongly discourage the idea to build a transformer by yourself (which your questions for the right number of turns implies). There are transformer and complete transformer boards which will output the correct voltage.
