FLYBACK VOLTAGE CONVERTER (EMBODIMENTS) Russian patent published in 2019 - IPC H02M3/155 

FIELD: electrical equipment.

SUBSTANCE: invention relates to the field of electrical equipment, radio electronics and intended for use in the secondary power sources as the constant-to-constant voltage converter. Flyback voltage converter in the first embodiment contains a MISFET with n-channel, the first primary winding of the transformer, transformer secondary winding, second capacitor, first and second rectifier diodes, output capacitor. In addition, flyback voltage converter contains the second primary winding of the transformer and the first capacitor. Flyback voltage converter according to the second embodiment additionally contains n isolating transformers (n – natural number, n ≥ 1), each of which contains one primary and one secondary windings of the transformer, n second rectifier diodes, n output capacitors, n positive and n negative outputs of the flyback voltage converter.

EFFECT: technical result is to increase the efficiency due to the fact that the regenerative power of scattered inductance energy is fully reused when discharging the first and the second capacitor in the transformer magnetization cycle, as well as the surface area of the conductor is increased and the impact of the skin effect is reduced due to the use of a transformer with two primary windings.
