- Abstract
Paper presents modified topology of the Vienna rectifier which has been applied in DC traction substation. Modification consists of replacing a pair of diodes with a pair of thyristors in each single-phase rectifier module. Fully-controlled rectifiers that consist of transistors are becoming more popular, also in traction applications. PWM rectifier, in comparison to the diode- or thyristor-based rectifiers, has higher power losses and its costs are higher. Proposed topology of the rectifier has got less number of transistors so the costs can be reduced. A 1,5 MW modified Vienna rectifier has been tested in computer simulation software.
