Abstract

There is provided a method (300), and a controller (160), for controlling a plurality of submodules (212) in a valve (224) of a power electronics device (290). The method comprises determining, by the controller (160), a time period in which selected submodules of the plurality of submodules (212) are to be switched in order to control an output voltage of the valve (224); determining, by the controller (160), for each of the selected submodules, a respective switching time, within the time period, based on a voltage demand for the time period and a voltage of each of the selected submodules, wherein at least one of the respective switching times is different to another of the respective switching times; generating, by the controller (160), a respective switching command (270) for each of the selected submodules; and providing, by the controller, the respective switching commands (270) to the valve (224), whereby to control the selected submodules to switch at the respective switching times within the time period.
