A DC-DC converter is provided which comprises an inductance element 10 having a plurality of in-phase windings N<SUB>B</SUB>, N<SUB>A </SUB>wound around a common magnetic core and connected to a load 5 ; a normal power source 16 for generating a reference voltage; a comparator 18 for comparing a voltage produced across winding N<SUB>A </SUB>with reference voltage V<SUB>R </SUB>of normal power souce 16 to produce an error signal. As a same electric current I<SUB>O </SUB>flows through the windings N<SUB>B</SUB>, N<SUB>A </SUB>of inductance element 10 in the opposite directions to each other to produce in magnetic core of inductance element 10 opposed magnetic fluxes which countervail each other and any kind of noise such as ripple and spike noises causing voltage fluctuation.
