FIELD: electricity.
SUBSTANCE: claimed systems and method of implementation for uninterrupted power supply source having positive DC bus, neutral DC bus and negative DC bus; in one embodiment as uninterrupted power supply source it includes circuit of battery charger having inductance coil and the first and second outputs of charger. The first switch connected to the first output of inductance coil is configured with possibility of connection of positive DC bus with the first charger output. The second switch connected to the second output of inductance coil is configured with possibility of connection of negative DC bus with inductance coil. Neutral DC bus can be connected to the second output of charger. Circuit of battery charger can be configured in order to obtain energy from at least one positive DC bus and negative DC bus for charging of accumulator battery which is connected to the first and second outputs of the charger.
EFFECT: providing improved distribution of energy in accumulator battery.
