Abstract (en)
[origin: WO2016026594A1] The invention relates to a method for adapting a dead time (t_dead) between the beginning of the opening process of a first switching element (1.5.1) and the beginning of the closing process of a second serially connected switching element (1.5.2) in a switching regulator (1.5) of a switching power supply unit (1), having the following steps: - a measurement voltage (U_out) across the second switching element (1.5.2) is measured, - the dead time (t_dead) is varied such that the deviation of the measured measurement voltage (U_out) from a target value (U_target) of the measurement voltage is minimized or limited, and - the first and second switching elements (1.5.1, 1.5.2) are actuated using the thus ascertained dead time (t_dead). The invention further relates to a device for carrying out such a method, comprising a measuring unit (2), a processing unit (3), and a control unit (4).
