The voltage regulator has an adjustable autotransformer structure; a coil is evenly wound on an annular iron core, and the brushes are in close contact with the polished surface of the coil wires under the action of spring pressure. The rotating shaft drives the carbon brushes so that the brushes move along the Sliding on the surface of the coil, changing the contact position of the brush changes the primary and secondary turns ratio of the transformer, so that the output voltage can be smoothly and steplessly adjusted within the voltage regulation range.
