DEVICE FOR NETWORK FILTRATION AND STEPPED STABILIZATION Russian patent published in 2019 - IPC H02J3/01 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering and can be used to prevent abrupt changes of current in circuits with devices powered from alternating current network, preventing long-term supply of excess voltage to load circuit, total energy saving of active energy and stabilization of voltage supplied to load at the specified discrete level. Device for network filtration and stepped stabilization, comprising a filtering coil with a core, which is included in the break of the linear wire, on which at least one magnetising coil is installed, connected between linear wires capacitor, at least two, for example, two, complementary coils with cores and control coils, electronic switches connected between one of linear wires and first outputs of control coils, second outputs of which are connected to second linear wire, electronic switches connected in parallel to complementary coils, additionally contains at least three, for example three, connected between linear wires measuring single-level devices, which outputs are connected to encoder inputs. Outputs of the encoder are connected to inputs of inverters connected by their outputs to electronic switches connected in parallel to additional coils, and are connected to inputs of delay devices. Outputs of delay devices are connected to electronic switches connected to control coils. Complementary coils are connected to each other in series circuit, which one terminal is connected to one of linear wires, and the second lead is connected to the first lead of the bias coil, which is connected to the second linear lead at the output of the device by the second lead. Entire series circuit consisting of complementary coils and a magnetising coil is connected in parallel to a circuit consisting of a coil, a filter and a load.

EFFECT: technical result of using the proposed invention is increase in the accuracy of operation by creating a stabilizing effect of maintaining voltage at the output, which does not depend on load current; increased number of stages of filtration, regulation and stabilization, reduction of full current in load with control of allowable limits of voltage reduction in load as per technical characteristics.
