Title:
NOISE CANCELING DEVICE AND ELECTRICAL DEVICE COMPRISING SAID NOISE CANCELING DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/059160
Kind Code:
A1
Abstract:
This noise canceling device (4) comprises noise canceling circuits (4P, 4N) for electrical wires (21P, 21N) on the positive electrode side and the negative electrode side, respectively. Each noise canceling circuit (4P, 4N) comprises: first windings (41P, 41N) serially inserted in the electrical wires (21P, 21N); second windings (42P, 42N) and third windings (43P, 43N) connected respectively to a first end (A) and a second end (B) of the first windings (41P, 41N); and common cores (40P, 40N). The first windings (41P, 41N) and the third windings (43P, 43N) are inversely coupled to each other. The second windings (42P, 42N) and the third windings (43P, 43N) are inversely joined to each other, and the terminals that are not connected to the first windings (41P, 41N) are connected to each other at winding connection points (C, G), and the winding connection points (C, G) are grounded.
