DIRECT CONVERTER AND SYSTEM WITH THIS TYPE OF CONVERTER Russian patent published in 2014 - IPC H02M5/257 H02M5/293 H02M5/297 H02P27/16 B60L9/12 

FIELD: electricity.

SUBSTANCE: invention is related to the area of electric engineering and may be used to convert alternating voltage or current to alternating voltage or current without intermediate conversion to direct voltage or current. Technical result lies in provision of arbitrary and continuous control of current passage from input phase leads to output phase leads of the direct converter. The direct converter (1) is equipped with n input phase leads (U1, V1, W1) and p output phase leads (U2, V2, W2), where n≥2 and p≥2, n·p double-pole switching elements (2) for connecting of at least one positive and at least one negative voltage between poles. Each output phase lead (U2, V2, W2) is connected in series with each input phase lead (U1, V1, W1) through one switching element (2).

EFFECT: in order to provide arbitrary and continuous control of current passage from input phase leads to output phase leads of the direct converter and exchange electrical energy between double-pole switching elements at least one inductance coil (3) is included to each serial connection.
