FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical engineering, to resonant converters of electric energy based on parametric resonance generators. Parametric resonance generator comprises a set of coils interconnected in series and forming a resonance circuit with a capacity. Device for periodic changing the resonance circuit inductance is installed on the electric motor axle. Parametric resonance generator and the device for periodic changing the resonance circuit inductance are made of the first and the second parametric resonance electric machines installed one above the other. Each of the electric machines has a stator and a rotor. Rotors of the two electric machines are mounted on a common shaft. In stator slots of the first and the second electric machines around stator teeth there are main inductance coils connected to each other and to the capacity into a separate resonance circuit of each electric machine. Each main inductance coil in the second electric machine has an additional winding. All additional windings of all inductance coils of the second electric machine are interconnected in series and together with the main inductance coils are made in the form of a Tesla resonance transformer, wherein the main inductance coils of the resonance circuit are the primary winding. Additional windings of the inductance coils are made in the form of a secondary winding. Outputs of the Tesla transformer secondary winding are connected via a rectifier or one more Tesla transformer, a rectifier and an inverter to the load and via a frequency converter with the resonance circuit of the inductance coils of the first electric machine. Rotors of the first and the second electric machines in the cross section have on the outer rim ledges and slots. Dimensions of a rotor ledge are equal to the total size of two teeth and two slots of a stator. Number of a rotor ledges is twice less than the number of a stator teeth in each electric machine.
EFFECT: technical result is improvement of power and decrease of dependence of produced power of the parametric resonance generator from the load.
