Autotransformer has great advantages of small-size, low cost and high efficiency. The adjusted ratio in voltages of audiotransformer is lower than the usual transformer under the same situation, which becomes more obvious when the distinction between primary and secondary&#**9; s voltage becomes less obvious. Generally, the voltage ratio of autotransformer is rarely more than 2.Autotransformer&#**9;s isolation much be designed based on high voltage for the connection of primary and secondary&#**9; s windings .But autotransformer can not be used as isolation transformer for the reason that they share the grounding point.
