Abstract
A method for the closed-loop control of the operation of a light source which is supplied with power by a DC/DC voltage converter, a manipulated variable being regulated by a setpoint value for an operational parameter of the DC/DC voltage converter being input, wherein the method comprises the steps of: increasing the switching frequency of the DC/DC voltage converter by an increase value prior to rapid changes in the setpoint value; waiting for a retention time; setting the new setpoint value; waiting for the end of a total retention time; and lowering the switching frequency of the DC/DC voltage converter by the increase value.
