FIELD: electricity.
SUBSTANCE: application: in the field of power supply. System comprises multiple modules of energy accumulation, multiple modules of voltage conversion and control module, in which module (50) for selection of maximum value takes on values (Vb1, Vb2) of battery voltages and brings them to the maximum value in module (54) of lower limit value limitation. Module (52) of maximum value selection takes on required values (Vm1*, Vm2*) of voltage and delivers their maximum value into module (54) of lower limit value limitation. Module (54) of lower limit value limitation produces reference value (Vh*) of voltage, limiting the value so that it does not drop below output value of module (50) for selection of maximum value. Commands (PWC1, PWC2) of voltage conversion modules switching are generated on the basis of control actions calculation with application of combination of control element with feedback by voltage and control element with direction connection by voltage, and calculation of control actions with application of control element combination with feedback by current and control element with direction connection by voltage accordingly.
EFFECT: suppression of electric energy shift between modules of energy accumulation and reduced electric energy losses.
