Abstract
A DC/DC converter for converting an input DC voltage between input lines into an output DC voltage between output lines includes: an AC current forward path connected via switching electric components to at least one of the output lines and at least one of the output lines; an AC current backflow path connected via same electric connections to at least one of the input lines and at least one of the output lines; and an auxiliary converter for compensating a sum of currents flowing via all forward and backflow paths, the auxiliary converter connecting one end of an compensation current path via two pulsed switches alternately to two lines at one side, the other end of the compensation path being connected to at least one line at the other side of the converter. The input lines are galvanically separated from the output lines by capacitances in all current paths.
