STEPPING-DOWN TRANSFORMER, AND INDUCTION DRIVE CIRCUIT, WHICH IS SUPPLIED BY SINGLE-PHASE MAINS AND USES SUCH DEVICE |
摘要 |
electrical engineering. SUBSTANCE: device has at least two single-phase forced- commutation rectifiers, which supply secondary windings of main drive transformer. Power of direct current passes through said main drive transformer and recuperates at secondary winding by means of single-phase forced-commutation rectifier, which operates as monitored stepping-up rectifier. Single-phase forced-commutation rectifiers operate in synchronism as voltage inverter. Another claim of invention discloses induction drive circuit, which is supplied by single-phase mains and uses such stepping-down transformer. EFFECT: increased functional capabilities. 7 cl, 3 dwg |
