Abstract

PURPOSE: To prevent biased excitment of a transformer, and intend to protect the main switch element, by providing an auxiliary coil which generated the magnetic field so as to deny the magnetic field of the primary winding, together with the transformer, in only a term when the primary winding current of the transformer is eddy current.
