Title:
DEVICE FOR COMPENSATING FOR VOLTAGE OR CURRENT
Document Type and Number:
WIPO Patent Application WO/2020/213997
Kind Code:
A1
Abstract:
The present invention provides an active compensation device for actively compensating for a first current input in a common mode to each of at least two high current paths connected to a first device, the active compensation device comprising: the at least two high current paths for transmitting, to the first device, a second current supplied by a second device; a sensing unit for sensing the first current on the high current paths thereby generating an output signal corresponding to the first current; an amplification unit for amplifying the output signal of the sensing unit thereby generating an amplified current; a compensation unit for generating a compensated current on the basis of the amplified current and flowing the compensated current through each of the at least two high current paths; a first disturbance protection unit connected in parallel to an output terminal of the sensing unit from which the output signal is generated; and a second disturbance protection unit connected in parallel to an input terminal of the compensation unit, wherein the first disturbance protection unit and the second disturbance protection unit include transient voltage suppression (TVS) diode elements.
