Abstract
A method for actuating a DC-to-DC converter, in particular a clocked buck-boost converter that includes at least two switch elements and an inductor or throttle and via which an input voltage is converted into a regulated output voltage, wherein the switch elements are actuated with a variable switch frequency using pulse- and frequency-modulated control signals, where the pulse- and frequency-modulated control signals are derived from a manipulated variable from a regulator, a voltage curve on the switch elements is continuously ascertained or monitored to determine the activation time of the switch elements and to start a new switch cycle, the switch elements are activated if a specified minimum period duration has been exceeded upon detecting a voltage minimum of the ascertained voltage curve on the switch elements.
