Title: Biased magnetization preventing circuit in high-frequency transformer
Inventor: KOUJI YOSHINOBU
IPC: H01F27/34
Filed: 1995-06-09
Abstract: PURPOSE: To make it possible to prevent biased magnetization in a simple setup, by using a resistor that controls a current carried to an input-side winding on the basis of positive and negative deviation values at an output voltage in a voltage inverter. CONSTITUTION: In a circuit, a resistor 30 is provided in series with a primary winding of a transformer 4. The transformer 4 is represented by an equivalent circuit made up of small resistors r1, r2, and g0, and reactance elements x1 and x2. In a high-frequency circuit with IGBT's, an inverter is operated at very high switching frequency, and a large deviation current is caused because of low resistance in the resistor r1 even when a very small positive and negative deviation factor is generated by positive and negative unsymmetrical waves at an input voltage V1 of the transformer 4. In this constitution, the resistor 30 is inserted in an input side of the transformer 4, and thereby a saturation phenomenon caused by biased magnetization is prevented by inserting a resistor Re with a relation of Re/r1.

The acute angle to the magnetic pole face of the magnet 6 is preferably 30 to 60 deg.. If the angle is less than 30 deg., the magnetic force is weak. If the angle is more than 60 deg., a toner projection takes place near the S-pole of the magnet and can cause a noise.
