ABSTRACT:
A device for regulating the exchange of energy between at least two generating and/or receiving, DC and/or AC electrical systems, (S.sub.0 . . . S.sub.n) for controlling the powers delivered or absorbed by said systems, these electrical systems being Y-connected to an oscillating circuit (OSC) by means of static switches (C.sub.p, Ca.sub.1 . . . C.sub.n), a controllable phase-shifting circuit (D) for driving the converters for producing at their outputs electrical values with a common frequency and with constrained phases; the oscillating circuits (OSC) oscillating at the above stated frequency for assuring temporary energy storage, and control means (MC) for feeding control signals as a function of the desired energy exchanges to the phase shifting circuits (D).
