Abstract

The present application relates to switched mode power supplies and provides a method of control in which the 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. The method uses a measure of supply voltage to provide for power factor correction. A non linear function is employed to the measure to trade-off power factor correction with output ripple.
