Abstract:
1. An automatic voltage regulator for converting an input voltage applied to an input terminal and outputting the converted input voltage to an output terminal, comprising: a main winding unit having one end thereof connected to the input terminal and the other end thereof connected to the output terminal, and having a plurality of main windings and a plurality of first switches for switching so that the plurality of main windings are selectively serially connected; a field winding excited in at least one of the main windings connected serially by the first switches of the main winding unit; a second switch for selectively connecting one end of the field winding to either a reference potential or the output terminal; a third switch for connecting the other end of the field winding 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 by switching control of the plurality of first switches, the second switch, and the third switch.
