MAGNETIC INTEGRAL SYMMETRICAL CONVERTER Russian patent published in 2014 - IPC H02M7/48 H02M3/335 

FIELD: electricity.

SUBSTANCE: invention relates to electrical engineering. Magnetic integral symmetrical converter with an integral function of a transformer and an inductor includes the following: an integral magnetic element having a magnetic core with three magnetic columns, which includes at least three windings (N_p, N_S1, N_S2) and at least one air gap for energy accumulation, where primary winding (N_p) and the first secondary winding (N_S1) are wound about the first magnetic column or both of them are wound about the second magnetic column and the third magnetic column, and the second secondary winding (N_S2) is wound about the second magnetic column, and a hollow output current flows along the second secondary winding (N_S2); a symmetrically operating inverter circuit with two outputs, which acts on primary winding (N_p); and a group of synchronous rectifiers (SR₁, SR₂), the control signals of electrodes of the lock of which and the control signals of electrodes of the lock of a group of diodes of a power supply switch (S₁, S₂) of the symmetrically operating inverter circuit with two outputs complement each other.

EFFECT: magnetic integral symmetrical converter can reduce losses on windings and scattered inductance of the primary winding side and the secondary winding side so that the technical result comprising high-efficiency energy conversion is achieved.
