Abstract (en)
[origin: WO2020151968A1] The invention relates to the actuation of an electric machine with a change between time-synchronous PWM clocking and angle-synchronous block clocking. It is proposed to provide an angle-synchronous clocking with adjustable voltage indicator length for the transition. In this way, jumps in the operating behavior of the electric machine can be minimized or optionally prevented completely during a change between time-synchronous clocking and angle-synchronous clocking.
