FIELD: electrical engineering.
SUBSTANCE: proposed invention relates to electrical engineering and can be used in three-phase power supply systems. Result is ensured by inclusion of a microprocessor control system into a three-phase active voltage rectifier, wherein control outputs of microprocessor control system are connected to control inputs of transistor power switches of bridge rectifier, and data inputs of microprocessor control system are connected to data outputs of alternating voltage sensors, output voltage sensor and input phase current sensors.
EFFECT: formation of stabilized voltage at output DC terminals of three-phase active rectifier for power supply of DC loads in conditions of presence of unbalance of three-phase system of supply voltages, which does not contain ripple with double frequency of supply voltage.
