Referring to fig. 1 and fig. 2, fig. 1 is a first structural schematic diagram of a voltage regulating device provided in an embodiment of the present application, and fig. 2 is a second structural schematic diagram of the voltage regulating device provided in the embodiment of the present application, where the voltage regulating device is applied to a transformer, where the transformer includes a coupling coil on a primary side and a coupling coil on a secondary side, and the coupling coil on the primary side is coupled with the coupling coil on the secondary side. The voltage regulating device comprises a switching assembly and at least one voltage regulating coil, wherein the switching assembly is used for selectively connecting a coupling coil in the transformer with the voltage regulating coil in series or removing the serial relation between the coupling coil and the voltage regulating coil. When the voltage regulating coil is connected with the coupling coil on one side in series, the voltage regulating coil is coupled with the coupling coil on the other side.
The embodiment is used for realizing the series connection of the coupling coil and the voltage regulating coil so as to change the number of turns of the coupling coil, thereby achieving the purpose of changing the transformation ratio of the transformer and enabling one transformer to be regulated into different transformation ratios. In this embodiment, the coupling means that a fluctuating current or voltage generates a magnetic field on one coil or one group of coils, and a magnetic field with a corresponding proportion is generated on another coil or another group of coils in the same magnetic field, so that the voltage or current in another coil or another group of coils changes with a corresponding proportion, thereby realizing the process of energy transfer from one coil to another coil.

Or, when the number of turns of the secondary side coupling coil is greater than that of the primary side coupling coil, the voltage regulating device is arranged on the secondary side coupling coil.

When the voltage regulator of the transformer described in this embodiment is disposed on the primary side, when the transformer needs to be applied to scenes with input voltages of different magnitudes, the primary side magnetic flux can be maintained constant by changing the voltage regulating coil (which is equivalent to changing the number of turns of the primary side coil) connected in series with the primary side coupling coil, so that the secondary side can output a specific voltage.
