| 摘要 |
The present invention relates to an automatic voltage regulator and a toroidal transformer, comprising: a main winding; a primary field winding excited in the main winding; a first switch unit for selectively connecting one end of the primary field winding to either a reference potential or the output terminal; a plurality of secondary field windings excited in the main winding; a second switch unit for selectively switching so that the plurality of secondary field windings are selectively connected to the primary field winding serially; a third switch unit for selectively connecting an end of a serial connection generated by selectively connecting the primary field winding and the secondary field windings to either the reference potential or the input terminal; and a control unit which regulates the level of an output voltage output to the output terminal.
