Abstract
A method of controlling a mains powered switched mode power supply e.g. used for driving an LED array with a constant current, in which a constant current converter is controlled using estimates of output current from the secondary side determined from measurements performed on the primary side. The method of control operates during a current half mains cycle based on an average of the estimates of output current determined during a previous one or more half mains cycles.
