Abstract
A method of operating a switched mode power supply comprising a switched mode converter and a control arrangement. The switched mode converter converts an input voltage to an output voltage and includes a primary winding, controllable switch based circuitry connecting the input voltage over the primary winding, a secondary winding coupled to the primary winding, and an LC filter including an inductive element and a capacitive element, wherein the output voltage is obtained as the voltage over the capacitive element and a duty cycle of the switched mode converter can be controlled by controlling the switch based circuitry. The switched mode converter is controlled depending on measurements of the input and output voltages in a hybrid regulated ratio control scheme. The power of the switched mode power supply is shut off or a current thereof is limited, when a current of the switched mode power supply reaches a maximum current.
