DRIVE METHOD WITH SHIFTING OF THE SWITCHING FREQUENCY AND DRIVE DEVICE

A method for driving a vehicle comprising at least two motors is provided. If a plurality of motors are fed from an intermediate circuit via inverters, the current in the intermediate circuit has a plurality of harmonics (−5th, −3th, −1st, +1st, +3rd, +5th). To prevent coupling capacitors of the int...

Beschreibung
Zusammenfassung:	A method for driving a vehicle comprising at least two motors is provided. If a plurality of motors are fed from an intermediate circuit via inverters, the current in the intermediate circuit has a plurality of harmonics (−5th, −3th, −1st, +1st, +3rd, +5th). To prevent coupling capacitors of the intermediate circuit becoming over-burdened, the switching frequency of the inverters is shifted in such a manner that the harmonics no longer fall into a resonance range.
