Abstract: According to a first aspect of the disclosure, there is provided a method of controlling a power output of an inverter. The method comprises measuring an output current of the inverter, determining a difference between the output current and a reference current, and controlling a reference input voltage of the inverter as a function of the determined difference. In a second aspect of the disclosure, there is described a system for controlling a power output of an inverter. The system comprises an inverter arranged to output a current as a function of a reference input voltage. The system further comprises a controller arranged to determine a difference between the output current and a reference current. The controller is further arranged to control the reference input voltage as a function of the determined difference. The method may allow for control of a photovoltaic inverter at a power less than its maximum capability for a given solar irradiation, which may avoid the problem of the photovoltaic array voltage rising above a level where the inverter can run.

Abstract: 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 (tg) of the time interval at which said generation of a current in the switching device occurs.
