Title:
NOISE REDUCTION CIRCUIT OF CONDENSER, AND POWER SOURCE DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/199021
Kind Code:
A1
Abstract:
According to the present invention, a grounding path (26) is connected between a device frame or a grounding potential (a grounding point 10), and conductive fixing members (metallic bands 18) for fixing condensers (14-1, 14-2, 14-3···14-N). The grounding path (26) is provided with an element (a high-frequency current reduction element 24) for reducing high-frequency current flowing through the grounding path (26), and suppresses noise current flowing through the grounding path (26). Therefore, the noise current due to stray capacitance or parasitic capacitance in the grounding path of the condensers can be reduced.
