摘要： A method for predicting pulse width modulated switching sequences for a multi-phase multi-level converter is presented. With a first predicted switching sequence, due to multi-phase redundancies, equivalent switching sequences are determined. From the equivalent switching sequences one switching sequence optimal with respect to a predefined optimization goal is selected. The selected switching sequence is used to switch the converter.
