A DC/DC converter circuit including an inductance 10, two controllable switches 12, 14 and a controller 16 for controlling the switches 12, 14 is configured so that it is able to operate in two permanently alternating operating time phases. The switches 12, 14 in the DC/DC converter circuit are arranged so that when the controller 16 is in the first operating time phase it closes the first switch 12 and opens the second switch 14 in achieving a flow of energy from the input of the DC/DC converter circuit to the inductance 10 and then when the controller 16 is in the second operating time phase it opens the first switch 12 and closes the second switch 14 in achieving a flow of energy from the inductance 10 to the output of the DC/DC converter circuit. Prior to switching from one operating time phase into the other operating time phase an intermediate time phase is inserted for safety reasons, in which both switches 12, 14 of the DC/DC converter circuit are briefly opened.
