Utility company electricity guidelines change from country to country. Just to illustrate, Asian and also European nations employ 220V AC while many other nations which includes the US, make use of 110V AC for their residence electrical supply requirements.
Which means electrical goods offered across various nations owning this kind of diversified voltage specifications are likewise dimensioned based on the individual country’s electric power supply specifications.
Consequently in India, all AC electrical goods are made for working with 220V AC, while in the US, the appliances are prescribed for 110V functions.
The difficulty takes place in case a specific device
Should we take the example of a YAMHA amplifier we locate that it’s stipulated for an 110V function thereby consumers in India need to involve a 220V to 110V coupler for working these imported items.
These types of AC to AC converters certainly grow to be important units under this kind of conditions. Most people may have possibly observed these fascinating switching products, nevertheless understand little how these converters essentially function. Let’s take a closer look into these awesome devices.
Should you remove the top lid of a 220V to 110V converter, you probably would possibly discover one particular component wired inside the system, that could be undoubtedly the transformer.
Commonly we appreciate transformers in the shape of step-down that happen to be typically utilized in compact AC to DC adapters. The major functionality of these compact transformers is to transform the high 220 or 110V AC to 6 or 12V for the specific low voltage gadgets which need 6 to 12V DC for working.
A converter additionally features a transformer, nevertheless here the transformer is meant for stepping down a 220V AC to a lower 110V AC.
The changing specifications merely count over the quantity of turns or the winding utilized in the specific transformer. The number of turns establishes the voltage ranges which should be made available at the output, while the thickness of the copper wire and the measurements of the iron core determine the current magnitudes from the unit.
The above elements are exactly proportional to one another, which means raising the range of turns or promoting the wire thickness and the iron core sizes subsequently boost the output magnitudes consequently.
As a result a 2000watt YAMAHA amplifier would need larger sized converter than a 1000watt YAMAHA amplifier.
The transformer utilized in these converters is definitely quite fundamental with their design. Here a particular particular continual coil is wound over a competently dimensioned iron core. Wire taps or terminations are available at specified measured areas over the whole coil. These terminals positioned at breaks are calculated for offering the needed voltage magnitudes to the load involved.
Once you observe the diagram, you might essentially notice how easy the winding seems. A sole winding turned around a core and switched at precise gaps for getting the needed step down voltages, 110V to be precise, with 220V provided at the input.
We could observe the complete wiring to be in the model of one particular copper coil, the 220V supply is fed at the end terminals of the coil, whilst the 110V output is acquired someplace at the midsection of the coil tap.
The above procedure could also be easily inverted, to be precise the winding could also be employed for producing 220V from a 110V input supply, hmmmm that looks very fascinating isn’t it, how?
Simply feed the input across the common and the 110V tap, so you will find a stepped up voltage across the end terminals of coil, that is across the 220V and the common terminals.
The core intended for such type of transformers are often available as “E” and “I” and the stuff is CRGO iron stampings.
Iron stampings are especially employed in place of one particular iron block for minimizing the development of eddy current and drawdowns on account of poor magnetic saturation and heat procreation.
Iron core by using electrically isolated stampings guarantees superior magnetic saturation and less eddy currents. This causes way less heat and improved performance of the transformer.
