Autotransformer (auto-transformer) is only one winding of the transformer, when used as a step-down transformer, withdrawn from the winding turns as part of the secondary winding; when used as a step-up transformer, the applied voltage is only applied to the winding - Part turns on. Usually it belongs to that part of the primary and secondary windings is called the common winding, and the remaining part is called the series winding, with the capacity of autotransformers compared with ordinary transformers, not only small size, and high efficiency, and the larger the capacity of the transformer, the higher the voltage. This advantage will become even more prominent. So with the development of the power system, the voltage level of increase and transmission capacity increases, autotransformers due to the large capacity, low loss, low cost and widely used auto advantages and disadvantages of the transformer: auto transformers Advantages: two windings overlap, thus saving some copper wire, smaller size, the structure is relatively simple. Autotransformer disadvantage: not completely isolated between the primary and secondary windings. In the step-down circuit, if the secondary winding accidentally disconnected, so that the output voltage value rises and as high as preliminary, and cause danger. The company's transformer design, production has been 10 years of history, for the exchange of 50Hz to 400Hz, the following circuit voltage of 1000V. Widely used in power transmission purposes or adjustable power output voltage available. Lighting, electrical machines, machinery and electronic equipment, medical equipment, rectifier devices. Product performance can meet the user a variety of special to
