Abstract
A method for determining an intermediate circuit voltage Uin an electrical system, which includes a battery, a DC-DC converter, a DC-AC converter, and an electrical machine. The battery is connected to the DC-DC converter, the DC-DC converter is connected to the DC-AC converter, and the DC-AC converter is connected to the electrical machine. An intermediate circuit of the electrical system is formed by the DC-DC converter and the DC-AC converter. A line-to-line voltage Û, which is applied to a conductor of the electrical machine, is determined, wherein a maximum degree of modulation mof the line-to-line voltage Ûis determined. The intermediate circuit voltage Uis determined according to the equation
