<p>A voltage-source drive converter for a rail vehicle includes two supply converters, a voltage link and a load-side converter with drive motor connected in series. The converters can be divided into sub-converters and are isolatable from a current bus of the voltage link, so that the drive motor can be connected in by means of switching over these sub-converters, to thus provide a fault-tolerant drive converter which is capable of providing the total traction force in the event of drop-out of a phase module, thus maintaining scheduled traffic.</p> |
