Abstract
A transformer, comprising: a closed ferrite magnetic circuit having an air gap; a rigid component filling a portion of the air gap; and, a flexible material filling the remainder of the air gap to substantially absorb vibrations of the ferrite. In the case of air gaps greater than approximately 1 mm, the flexible material fills approximately 1 mm of the air gap and the rigid component fills the remainder of the air gap. The rigid component may be of non magnetic, synthetic resin material. The flexible material may be a one component mastic, for example polysulfur, polysulfate polysulphide or polyurethane. The flexible material may also be a silicone type mastic, for example a neutral silicone.
