The invention comprises a circuit arrangement with a first direct voltage to an alternating voltage transforming unit, an alternating voltage to a second direct voltage transforming unit, and a second direct voltage smoothing filter, connectable to a load, whereby the first direct voltage to an alternating voltage transforming unit has an inductance whose one connection is connected to a mutual connecting point for a two series connected rectifiers, and wherein the alternating voltage to a second direct voltage transforming unit includes a parallel related rectifier. A back current through one of two parallel related rectifiers, formed at the switching period of the alternating voltage, and a therefrom originating power contribution to the inductance, is redistributed by a power contribution redistributing organ, belonging to the transforming unit, in order to reduce the losses appearing, for instance in the series connected rectifiers. |
