PCT No. PCT/EP90/00904 Sec. 371 Date Mar. 25, 1991 Sec. 102(e) Date Mar. 25, 1991 PCT Filed May 28, 1990 PCT Pub. No. WO90/15469 PCT Pub. Date Dec. 13, 1990.An electric converter comprising at least three reactive elements (1, 2, 3) connected in series, and a switching device comprising a switching transistor (4) and a diode (5), the switching transistor operating at a high frequency so that it becomes conductive for a fraction of each period of said frequency. The transistor (4) and the diode (5) are connected to the connection points (12, 13) between the reactive elements (1, 2, 3) so that the diode (5) is conductive only when the transistor (4) is non-conductive and so that it is non-conductive each time the transistor (4) becomes conductive. This device is used to control the electric current from a DC power supply to a load.
