FIELD: electricity.
SUBSTANCE: power required for supply of DC load is extracted with the help of a fully controllable n-phase WPM-rectifier of transistor type by means of balancing currents, at least from one phase, making a group of balanced phases, - so that the current that remained in each phase of the specified group picked by a non-balanced load, has a module value equal to either the one that has been previously determined or equal to the value of the current module in the reference phase, which has been previously selected from n-supplying phases of unbalanced system of power supply according to the condition of the maximum value of the current module.
EFFECT: increased efficiency of power usage by reduction of non-efficient losses in power flow caused by unbalance of phase currents.
