NETWORK FILTER Russian patent published in 2016 - IPC H02J3/01 

FIELD: electronic equipment.

SUBSTANCE: invention can be used for reduction and smoothing of pulse current change in circuits with devices supplied from AC network, for prevention of long-term supply of excessive voltage in load circuit and for total energy saving of active and reactive power. Network filter comprises inductance coil included in the gaps of each linear wire and current filter inductance coil with core with at least one additional winding, connected between linear wires capacitor and at least two filter-adjusting circuit, the input of each of which is connected to the output of one of additional windings; connected in series in a linear wire of the main coil filtration and create a countercurrent flow and at least one, for example two counter-current inductances with cores and control windings, measuring device with measuring circuit, at least one, for example, two electronic switches, connected between one of the linear wires and first outputs of control windings, the second outputs of which are connected to one of the linear wires, at least one, for example two, electronic switches connected in parallel to counterflow inductances, outputs of the measuring device are connected to electronic switches and switches the measuring circuit is connected to the output of the filter, and the main coil creating counter current is mounted at least one coil of inductance.

EFFECT: device provides a technical result - lets you save electricity consumption load.
