FOUR-TIME MAGNETIC SEMICONDUCTOR FREQUENCY MULTIPLIER Russian patent published in 2015 - IPC H02M5/22 H02M5/14 

FIELD: electricity.

SUBSTANCE: invention relates to converter equipment. Four-time magnetic semiconductor frequency multiplier comprises a three-phase transformer with artificial earthing point in the primary winding and two secondary windings with the same level of output voltage. Four saturable reactors are connected to the transformer secondary windings and each reactor has two sections of windings coupled as per the bridge circuit. One bridge diagonals are connected to the transformer secondary windings while the other ones are interconnected and active inductance load is coupled to them. One section of windings of the saturable reactor and load are shunted by half-wave keys, at that shunting keys and load key are interconnected and connected to the control unit by the keys.

EFFECT: higher power factor.
