A voltage space pointer with a rate (U) and angle (arg(U)) forms a desired voltage system (UR.soll, US.soll, UT.soll). A no-voltage (U0) is formed from the desired voltage system, the angle and a control angle ( phi ). The voltage system resulting from the total of the no-voltage and desired voltage systems is fed to a pulse-width modulator (2) to form control signals (SR,SS,ST) for semi-conductor power switches in a frequency converter. |
