Beschreibung
Zusammenfassung:	The invention relates to a method for controlling a drive system of a rail vehicle. The drive system comprises at least one DC voltage intermediate circuit with at least one intermediate circuit capacitor to which an intermediate circuit voltage is applied during the operation of the drive system, a converter which is connected to the DC voltage intermediate circuit and which comprises a plurality of power semiconductor switches, a drive motor which is connected to the converter and which is designed as a three-phase synchronous machine excited by permanent magnets, and a controller for controlling the power semiconductor switches of the converter, wherein the power semiconductor switches are controlled by the controller during a motor operation and a generator operation of the drive motor such that the intermediate circuit voltage is converted into a multiphase AC voltage. The invention is characterized in that in an idling operation of the drive motor, the control of the power semiconductor switches is interrupted on the basis of a voltage induced in the converter by the drive motor.
