Disclosed is a DC-DC converter for suitably converting the voltage of a solar panel into a desired output voltage to be supplied to various observation equipment installed in an artificial satellite. The DC-DC converter 10 comprises an input coil L1, a first intermediate capacitor C1 and a first intermediate coil Lm1 connected in series between positive and negative terminals of an input voltage source E, a switch S and a diode D having their one ends connected to a node a of the input coil L1 and the first intermediate capacitor C1, a second intermediate coil Lm2 connected between the other end (node d) of the switch S and the negative terminal of the input voltage source E, a second intermediate capacitor C2 connected between the other end (node c of the diode D and the node d and a load R connected to the node c through an output coil L2.
