ABSTRACT:
A noise-shielded transformer is constructed with a toroidal core having mounted thereon a secondary winding, a bifilar shield winding, a conductive plate, an insulating member, a high voltage winding, and a primary winding. The secondary winding is located inside the other windings, making the assembly work easier and increasing the noise shielding effect. Multiple shielding, by the bifilar shield winding and the conductive plate, increases the capacitance between the secondary winding and ground and decreases the capacitance between the primary winding and the secondary winding, so that the noise eliminating characteristic with respect to pulse-property noise and high frequency-property noise is enhanced substantially. It is also possible to obtain a grounding effect and a noise-bypass effect by connecting a resonance condenser from ground to one end of the bifilar shield winding. Additional suppression of noise conduction is obtained by utilizing the high voltage winding to greatly increase the electrical potential difference between the primary winding and the secondary winding.
