Abstract
A DC/DC converter converts an input DC voltage into an output DC voltage. The DC/DC converter includes an input capacitor, an inductor, an electronic switch, a diode, an output capacitor and a control unit, wherein the control unit controls the first electronic switch as a function of the signals fed to the control unit. The input capacitor is connected between the input voltage and ground or zero point, and the inductor is connected between the input capacitor and the electronic switch. A second electronic switch, which the control unit can drive by means of a switching signal, is disposed between the load and the ground or zero point, and a second diode embodies a connection between the output of the load and the input capacitor. The control unit is fed the value of the input voltage.
