FIELD: electricity.
SUBSTANCE: power supply source comprises power supply modules, each of them comprises an input stage and an output stage. The input stage generates the intermediate voltage, and the output stage provides DC power voltage to the specified intermediate voltage. The input stages are controlled by, at least, the first common control signal with the common duty cycle, and the output stages are controlled by, at least, the second common control signal with the common duty cycle.
EFFECT: improving efficiency of power supplying.
