Abstract

A method of determining time intervals between switching events for a switching device in a power converter is provided. The device is coupled to a direct current source to provide an alternating current output at a particular switching frequency. The method comprises selecting an initial length of time interval 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 and obtaining current value for the switching device when the length of the time interval is changed. The current values are used to detect generation of current. From the change made to the length of the time interval a length is determined of the time interval at which said generation of current occurs. Fig.3
