<p>A DC-to-DC converter (42) comprises a DC-to-AC converter (52) and an AC-to-DC converter (56) connected in series with a transformer (54), both the DC-to-AC converter and the AC-to-DC converter comprising semiconductor switches (58, 62). A method for controlling a DC-to-DC converter (42) comprises the steps of: determining a DC input voltage (82) and a DC output voltage (84) of the DC-to-DC-converter (42); determining whether a switching condition (C) based on the DC input voltage (82) and the DC output voltage (84) is fulfilled; and generating a switching signal (98, 100) with switching pulses (140, 142) for switching the semiconductor switches (58, 82) of at least one of the DC-to-AC converter (52) and the AC-to-DC converter (56), wherein the generation of switching pulses (140, 142) is blocked, when the switching condition (C) is not fulfilled.</p> |
