Electrical regulation and energy transfer circuit

Claim 1

A regulating circuit for regulating an electrical parameter to be controlled by transferring electricity between first and second networks, said circuit being a bidirectional current circuit which provides electrical isolation between said first and second networks and which includes a power stage (13) having a plurality of power stage switches, the circuit being characterized in that it further comprises: power stage drive means for driving said switches in response to a control signal; a transformer stage having a primary and a secondary and which is bidirectional from an energy exchange point of view and which is peak current limited, said transformer stage delivering a voltage and a current which are regulated and providing DC isolation between said first and second networks; a clock module; a power stage control system comprising an impedance matching circuit and a current controlled section receiving inputs from said clock module, said impedance matching circuit and said first network and providing an output signal as said control signal to limit a peak current through at least one of said switches and to limit a DC current at an output of said regulating circuit; and a push-pull stage which is bidirectional for current and which is coupled to said primary of said transformer.
