Abstract

A vehicle is supplied with AC power from an AC source (20) via an overhead line (30) and a rail (40). The AC power is converted, via a transformer (70) and a power converter (100), into DC power for driving a DC motor (80). A smoothing inductor (75) reduces the ripple in the DC. A field winding (85) of the DC motor (80) is supplied from a dedicated power source (90). The field winding (85) is poled in order to utilise the braking power. The power converter (100) comprises four thyristors (101 to 104) which are split between two groups (P1, P2) of bridge arms. Each bridge arm contains one thyristor. In this thyristor bridge, the thyristors 101, 104 are turned on during the positive half-cycle of the AC voltage and the thyristors 102, 103 during the negative half-cycle. At the same time, one group (P1) of bridge arms is controlled at a minimum control phase-lead angle (ssmin) and the other group (P2) at a control phase-lead angle (ss) which is greater than the minimum control phase-lead angle (ssmin). In the case of this power converter, high-frequency components in the AC are reduced during the conversion from DC into AC (braking power utilisation).
