A recuperative three-phase rectifier relates to electric engineering and can be used as a DC source power supplied from three-phase network and can provide DC energy recuperation in a network. Such a source can be used for power supply of for example a frequency converter, at that in the drive breaking modes energy return to the network will be provided. The recuperative three-phase rectifier comprises a thyristor bridge with six thyristors, a choke, four diodes, four switches, an output energy storage with capacitors and a control circuit, a high-frequency transformer, a half-bridge converter. The technical result consists in prevention of reactive power consumption in recuperative mode, decrease of set inverter power, improving efficiency and increase of consumer quality. |
