Abstract

A method and control system for controlling a switching device in a power converter according to a modulation scheme. The switching device couples a DC source to provide an AC output at a particular switching frequency. The method comprises switching the switching device in switching periods (priority ii) between active configurations (i) a finite voltage and inactive configurations providing a zero voltage. The ratio between the total time period in which the switching device is in an active configuration and the total time period in which the switching device is in an inactive configuration is the same for each switching period and is determined according to the voltage at the AC output. However, in each switching period, there are at least two time periods in which the switching device is in an inactive configuration, and the ratio between those at least two time periods is dependent on temperature.
