Autotransformer is the coupling transformer, this transformer (also called linear transformer) structure is simple, the cost is low, the input/output and zero line sharing, vice side of the transformer is part of the primary side, first and second side with a winding together, like a line of two coils, two coil is to use the current large and small sent cutting lines, to transformer, generally used in dc booster, transformer's output and input has a direct electrical contact, safety performance is poor.An autotransformer is similar to a three-terminal adjustable resistor.Because direct current cannot be directly boosted, it needs to go through electronics and other components.It is usually used to adjust the voltage of the equipment.

The linear transformer needs to transmit ac signals with different frequencies and amplitudes, so the magnetic leakage should be small and the shielding should be good.

The difference between current transformers and non-Linear Transformers

The input and output voltage of the linear transformer is fixed according to the ratio of turns, such as the power frequency transformer.

The input and output voltage of the nonlinear transformer is based on the conservation of energy and is controlled by the PWM of the switching tube, such as the high frequency transformer.
