ABSTRACT:
A circuit for applying a direct current to a winding. One end of a primary winding of a transformer is connected to a first transistor via a resistor. The other end of the primary winding is connected to a second transistor. The first and second transistors constitute a current mirror circuit. By by-passing through a capacitor, no alternating current flows in the first transistor. The primary winding of the transformer includes a center tap and an AC/DC superimposed signal is input to the primary winding via the center tap. In the primary winding, DC components flow so as to mutually negate DC-magnetization. As a result, there is no need to provide a gap in a magnetization circuit and the construction of the whole circuit including the transformer can be miniaturized with improved characteristics.
