FIELD: power converters. SUBSTANCE: device has master and slave single-phase self-excited generators which have saturating transformers, each of which has primary winding and feedback winding. In addition device has synchronization winding, which is located on transformer of master generator and which is connected in series aiding to primary winding of slave self-excited generator. Slave generator transformer has synchronization winding which is connected in series-opposing to circuit of primary winding of master generator. Both transformers have additional feedback windings, which are connected to circuits of feedback windings in series aiding and opposing respectively for slave and master generators. Rate of transformation between primary and synchronization windings of slave generator is equal to rate of transformation between corresponding windings of master generator. Ratio of number of turns in additional windings and feedback windings is equal to ratio of number of turns in synchronization and primary windings. Device may be used in devices for electric power supply and electric drives. EFFECT: doubled precision of phase shift angle between output voltage levels, ; efficiency of converter is increased by 10 %. |
