DEVICE FOR CONNECTING CONTROLLED VOLTAGE INVERTER TO DIRECT CURRENT VOLTAGE SOURCE Russian patent published in 2014 - IPC H02M1/00 H02M1/36 

FIELD: electricity.

SUBSTANCE: device comprises current limiting circuits, one circuit per each input terminal of a rectifier, each circuit couples the input terminal of the above device connected to one of the output terminals of the above voltage source with the output terminal of the above device connected to one of the input terminals of the controlled voltage rectifier; each current limiting circuit consists of an inductive element, the first and second reactors, a capacitor as well as the first and second switches, in each current limiting circuit in the device there is an auxiliary parallel damping resistor and the third switch, which are coupled between the first terminal of the inductive element and the first terminal of the capacitor.

EFFECT: reduction of dimensions and weight for the claimed device intended for connection of the input voltage device to the alternating voltage source, including weight and dimensions of the bank of capacitors in the current limiting circuits, and improvement of the dynamic performance at the non-controlled charge stage of the output capacitor of the input voltage device.
