In a method of DC voltage—pulse voltage conversion, DC voltage is provided; a succession of controlling square pulses having adjustable pulse ratio is generated; an inductive load is periodically connected to outputs of a source of the DC voltage using the succession of the controlling square pulses; pulse current flowing through the inductive load is generated; a predefined value of resistance of an electronically-controlled resistor included in a circuit of the pulse current flowing through the inductive load is formed, and the pulse current is adjusted by the electronically-controlled resistor, whereby adjusting the level of pulse electromagnetic noise radiated to the environment is achieved.
