FIELD: electricity.
SUBSTANCE: system comprises diverse sources of supply and a power accumulator, outlets of which via ac-dc (ac-dc-ac) converters are connected to load buses, and load outlets via power and voltage sensors are connected to inlets of control systems of each ac-dc (ac-dc-ac) converter. As ac-dc (ac-dc-ac) converters are switched, the outlet of their control systems is supplied to the inlet of upper level control system, and its outlet is connected to control circuit of switches of the specified ac-dc (ac-dc-ac) converters.
EFFECT: provision of guaranteed uninterrupted power supply to a passive load.
