摘要： There is provided a method and control system for controlling a switching device in a power converter according to a modulation scheme. The switching device couples a direct current (DC) source to provide an alternating current (AC) output at a particular switching frequency. The method comprises the step of, in each switching period, switching the switching device between active configurations providing a finite voltage at the output and inactive configurations providing a zero voltage at the output. The ratio between the total period of time in which the switching device is in an active configuration and the total period of time in which the switching device is in an inactive configuration is the same for each switching period and is determined according to the desired 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 changed in dependence on temperature associated with the switching device.

摘要： A method is provided of determining a time interval between switching events for a switching device in a power converter, the switching device being for coupling a direct current (DC) source to provide an alternating current (AC) output at a particular switching frequency. The method comprises selecting an initial length of a time interval between a first switching event and a second, subsequent switching event for the switching device and obtaining a current measurement value for the switching device when the time interval between the first switching event and the second, subsequent switching event takes said initial length. The method further comprises changing the length of the time interval between the first switching event and the second, subsequent switching event and obtaining a current measurement value for the switching device when the length of the time interval is changed. The current measurement values which have been obtained are used to detect generation of a current in the switching device. It is then determined, from the change made to the length of the time interval and the current measurement values obtained, a length (t g ) of the time interval at which said generation of a current in the switching device occurs.
