Document Type and Number:
WIPO Patent Application WO/2012/055635
Kind Code:
A3
Abstract:
Method for operating an electric drive system (1), in particular of a motor vehicle, wherein the drive system (1) has an energy source (2) from which an induction machine (5) of the drive system (1) is supplied with electrical energy via a DC/DC transformer (3) which can be operated, in particular, as a boost converter, and a power inverter (4) of the respective drive system (1), wherein in a first operating mode an intermediate circuit voltage (UZK), which is connected to the input of the power inverter (4), is conducted as a function of the power demand of the induction machine (5).
