ELECTRIC HIGH-FREQUENCY TRANSFORMER Russian patent published in 2011 - IPC H01F19/04 H01F27/28 

FIELD: electricity.

SUBSTANCE: in electric high-frequency transformer, which contains low-voltage winding connected through capacitor to high-frequency generator and high-voltage winding performed in a form of spiral coil with winding length equal to quarter of current wave and voltage wave length, electric voltage and thickness of conductor electrical insulation is different for each section and increases while section is receding from beginning of spiral winding according to the formula: where cosφ_i; - specified current value of i section; where V_i, - voltage at the end of i section; V₀ - voltage at the end of spiral winding; δ_i - thickness of electrical insulation in i section,

EFFECT: increase of insulation strength of high-voltage winding.
