Abstract (en)
[origin: WO2010000548A2] The invention relates to a method for optimizing space-vector pulse width modulation. A voltage (Uz) is connected to a load (1) by combining discrete switching states of a plurality of switches (T1, T2, T3, T4, T5, T6) to control the load (1), the load (1) being switched zero voltage by two of the switching states (0, 7). The method according to the invention is characterized in that least one of the zero voltage switching states (0, 7) is omitted during a pulse width modulation period, thereby increasing the maximum control degree.
