FIELD: electricity.
SUBSTANCE: invention is related to devices intended for the generation of an exciting signal. The exciting PWM signal has a plurality of switching-on and switching-off sections, which determine the first working cycle for the regulation of a pump unit flow rate, at least partially. At least one section out of the switching-on sections for the exciting PWM signal is modulated by the pulse width in order to define the second working cycle for at least one section out of the switching-on sections for the exciting PWM signal. The second working cycle regulates, at least partially, the percent ratio of the determined current potential supplied to the pump unit.
EFFECT: potential generation of the exciting PWM-signal having a certain current potential.
