Abstract

See full text

A transformer includes a first switch, a first winding, a second winding, a third winding, a first current direction control unit, a second current direction control unit and a loading capacitor. The first switch is coupled between the second winding and the third winding. The first winding is disposed at a primary side and coupled between an input voltage terminal and a first ground. The second winding is disposed at a secondary side and coupled between a second ground and the first switch. The third winding is disposed at the secondary side. The first current direction control unit is coupled between the second winding and an output voltage terminal. The second current direction control unit is coupled between the third winding and the output voltage terminal. The first switch is turned on for adjusting a winding ratio when the transformer is used to output a high voltage.
