FIELD: electrical engineering.
SUBSTANCE: three-phase high-voltage frequency converter relates to electrical engineering. In each output phase (A, B, C) N (N=1,2…) of rectifier-inverter units (5), which are connected by inputs to secondary windings (4) of three identical network transformers, are connected in series. Windings (4) have phase shift of voltage vectors. Units (5) make three outputs. Primary windings (1, 2, 3) of transformers are made with taps and phases of network windings of each transformer are connected to different taps so that sum of deviations of voltages of phase taps at each transformer is equal to zero, besides, each transformer supplies units (5) of same level.
EFFECT: three-phase high-frequency frequency converter is proposed.
