Abstract

A method of driving a power conversion system is provided, the power conversion system comprising a DC source and an inverter configured to receive DC power from the DC source, the inverter comprising one or more AC terminals for supplying AC power at an output frequency and an inverter switching network comprising a plurality of inverter switches for converting the DC power to the AC power. The method comprises: applying control signals to the inverter switching network in accordance with a selected switching sequence, wherein a switching sequence is applied corresponding to a desired sector of a switching scheme in which a demand vector is currently located; storing a plurality of simultaneous switching schemes; and at low output frequency, applying a simultaneous switching sequence. A corresponding power conversion system and switch controller for a power conversion system are also provided. Fig. 9
