Current control of a pulse width modulated power converter
Abstract:
The present invention relates to a method for the current control of a pulse width modulated power converter for an electric machine, in particular a pulse width modulated inverter connected to the electric machine. The machine and the inverter thereby comprise a plurality of phases, and the current control is carried out by means of a control loop comprising a modulator for the calculation of switching times for a pulse generator for producing a pulse width modulated control voltage for each phase. Furthermore, the present invention relates to a corresponding device for current control of an inverter connected to an electric machine.
