Voltage-compensation interface device with low storage of energy in capacitive form and electrical network comprising this device

摘要

The device has a voltage compensation circuit (3a) coupled between disarrayed and arrayed parts (A, B) of a network in case of voltage fall in the disarrayed part resulting from disturb function of the network. The circuit produces and assures serialization of compensation voltage (Vs) between the parts obtained from the voltage fall in the disarrayed part, to constantly maintain the voltage in the arrayed part. The circuit is connected in parallel to a switch (K1) to insert the circuit between the parts during opening of the switch for assuring the serialization of the compensation voltage. The switch is constituted by semi-conductor elements such as transistors.
