Abstract
In a method for determining current in a polyphase machine connected to a DC voltage source, a DC link is provided with a DC-link capacitor and, per phase, a high-side switch and a low-side switch. A measurement of the voltage curve across the DC-link capacitor is undertaken. The current of the DC voltage source and/or one or a plurality of phase currents are/is determined from the measured voltage curve.
