摘要
An apparatus for controlling a switching DC-DC converter with a first half-bridge circuit including a first switch and a second switch, with a second half-bridge circuit including a third switch and a fourth switch and with an inductance connected between the center taps of the first and the second half-bridge circuit includes, according to embodiments, a control unit that is configured to adapt, in dependence on an input voltage and an output voltage at the switching DC-DC converter, a switching frequency of the switches of the DC-DC converter, the duty cycles of the first and fourth switch and the time delay between switching on the first and the fourth switch. The control unit is configured to determine the switching frequency, the first duty cycle, the second duty cycle and the time delay based on an output current of the switching DC-DC converter.
