The present invention has an object to develop a converter allowing dielectric strength of a booster transformer to be reduced by half for miniaturization and security thereof. To achieve this object, the booster transformer is provided with first and second secondary coils so that, every time a switching element is turned ON, the first secondary coil generates positive voltage in reference with the negative terminal potential of a DC source while the second secondary coil generates negative voltage also in reference with the negative terminal potential of the DC source and a sum of these positive and negative voltages is output from the converter as a composite voltage.
