The difference between a double wound step up transformer and an auto transformer is the double wound on the step up transformer and the single wound on the auto transformer.
The most important advantage is that the secondary circuit is electrically-isolated from the primary circuit.

"Auto" refers to the single winding used an auto transformer.
One can purchase an Auto Transformer from websites like Mastech Power Supply, Amazon, Ali Express, RS-Online, eBay, Foster Transformer, Farnell and Alibaba.
(An auto-transformer can be dangerous because the primary is not electrically isolated from the secondary. If the auto-transformer is connected to mains power, this is the equivalent of sticking your fingers directly in the wall plug; not a good idea!) aka deceptacons like megatron will kill you.
An auto transformer has one winding with the output being tapped at some point and therefore has no isolation between primary and secondary. This may make it unsafe or illegal in some applications. A common power transformer has separate windings.
A transformer or, more-properly, a mutual transformer, has two windings, the primary and the secondary, which are electrically-isolated from each other, with the secondary voltage induced through mutual induction. An autotransformerconsists of one tapped winding, so the secondary circuit is not electrically isolated from the primary circuit. An autotransformer may be used to either increase or decrease the primary voltage, depending how it is connected.
Buy a double wound step-down transformer (230/115 volts) of he appropriate capacity (kva) . You may have to replace the plug on your oven to match the output socket of the transformer if you buy this in England. Do not buy a single wound (auto transformer) as it can be extremely dangerous if it is wrongly connected.Alwyn.
yes we can place auto transformer in place of original transformer
The main advantage is that its cheaper. Since U do not have 2 separate windings, it's cheaper to manufacture. Unfortunately, it's not isolated.AutoTransformers are used for converting USA-2-Euro voltagesand vice-versa. BUT, since one leg is common to both, U do nothave electrical isolation from primary to secondary.
because the copper is saved in the auto transformer that is the ratio of weights of copper in auto transformer to normal transformer is (1-(1/a)) where a is transformer ratio
auto transformer is a one winding transformer which is are used for step up and step down voltage without chang its power and friquncy
"Auto" refers to the single winding used an auto transformer.
the auto transformer is the one winding transformer. it ismaily used in practical purpose.

by using auto transformer or auto stablizers
Variable transformer may also refer as auto transformer. We can vary the output voltage of the transformer. But in the ordinary transformers output voltage is already designed.
A mulit tap ballast is in fact an auto transformer.
