FIELD: test technology.
SUBSTANCE: invention relates to frequency converters and can be used in tests of transformers. Transducer comprises network transformer 1, rectifier 11, filter 12, three single-phase inverters 13, single-phase output transformers with primary windings 2–4 and secondary 5–7, which are connected to switch 8, 9 of three-phase mode in single-phase. Transformers are equipped with tertiary windings 15–17 connected to each other in open triangle, to outputs of which additional switch contact 14 is connected. Contact 14 is connected to capacitor 18 providing resonance at frequency of one of higher odd harmonics (5th, 7th, 11th).
EFFECT: improved shape of output voltage.
