FIELD: electrical engineering.
SUBSTANCE: proposed unit designed for use as three-phase rectifier characterized in improved electromagnetic compatibility with load and supply mains due to utmost use of potential capabilities of double-channel flow conversion at optimal size and mass has two rectifier bridges 4, 8 whose outputs are interconnected in parallel and inputs are connected to secondary three-phase windings 3, 7 of transformers 1, 5, respectively. Mentioned windings have different circuit layouts. Primary windings 2 and 6 of transformers 1 and 5 are cumulatively series-interconnected in phase-for-phase manner. Bridges 4 and 8 operate alternately in two- and three-gate modes, respectively.
EFFECT: improved quality of output voltage due to eliminating current unbalance caused by voltage amplitude unbalance in channels.
