How do i convert from 380 volts to 220 volts?
If these are the exact voltages that you need you will need an auto transformer to obtain these voltages. If these voltages are nominal voltages and are of a three phase four wire configuration, the 220 voltage can be obtained from the three phase legs to the neutral (ground) connection. The equation to use is 400/1.73 = 231 volts.
How many coils does a autotransformer have?
only single coil is use as a primary and secondary coil in a auto transformer.
Why you not use auto transformer for distribution purpose?
because autotransformer used for both purpose step up and step down but dustrubution need step down in case of this autotransformer not used for dustrubtion purpouseAnswerBecause an autotransformer (not 'auto transformer') does not provide electrical isolation between the secondary and primary.
What type of transformers are used to step down a voltage for general use and what type of systems are they classified as?
The transformer you describe is being used as a step-down transformer, and is classified as an electrical machine. The transformer could either be a mutual transformer, consisting of two, electrically-isolated coils, or an auto-transformer which uses a common coil between its primary and secondary circuits.
Conversion of 2-winding transformer into auto transformer?
Yes, you can use a mutual (2-winding) transformer as an autotransformer, by connecting the two windings in series. For example, if you have a 240:120 V transformer, connecting the two windings in series and supplying the 240-V winding with 240 V can give you a secondary voltage of 360 V. But you must take into account the polarity of the transformer, and realise its capacity will change.
What is the application of pluse transformer?
why should we use pulse transformer rather than ordinary transformer

How do you start a motor without a starter?
By the use of auto transformer and bridge rectifier we can start dc motor.
How can you use 1 transformer in Inverter and Battery charger?
Those are special type transformer used for both step down and step up in a single transformer ,they are specially designed . their wire thickness in both winding is thicker than ordinary step up or down transformer.and they are costly too.

You can use neutral to autotransformer?
Yes, but the transformer must have both the hot and neutral to work as designed. A auto-transformer is not a variable resistor that could reduce current/voltage by a change in the resistance which could be used in the hot and or neutral wire. An auto-transformer is designed to have the hot wire and neutral on each end of the winding with a variable tap in between. The resistance of the transformer and the inductance will effect the circuit to a limited way if placed in the neutral but this effect will not vary the voltage over the full range, the amount of voltage reduction will vary with the load's current draw, see ohms law. Neither a resistor or a auto-transformer connected in the neutral line only will increase the voltage above the level of the input like a correctly connected auto-transformer . Stanley

What is the use of ideal transformer?
Ideal transformer is useful in understanding the practical transformer..i does't have losses...
Can you use a transformer to convert modified sine wave to pure sine wave?
we cannot use transformer because transformer cannot change frequency . . .
