Abstract:
A method and an arrangement of limiting temperature variations in a semiconductor component of a switching converter, the method comprising determining a quantity relating to operation temperature of the switching converter, determining temperature of the semiconductor component, selecting a maximum value of switching frequency of the switching converter based on the determined quantity relating to operation temperature of the switching converter and the temperature of the semiconductor component, and limiting the switching frequency of the semiconductor component of the switching converter to the selected switching frequency.
