Title:
ELECTRIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/048978
Kind Code:
A1
Abstract:
A first power conversion circuit (150a) and a second power conversion circuit (150b) are connected in common to a power receiving part (110) connected to an input power supply (10) via a first noise filter circuit (25a) and a second noise filter circuit (25b). A first inductance (La) in a first path formed, through the first noise filter circuit (25a), between power supply input nodes (N0, N1) of the power receiving part (110) and a second inductance (Lb) in a second path formed, through the second noise filter circuit (25b), between the power supply input nodes (N0, N1) are adjusted so that the ratio (La/Lb) of the first inductance to the second inductance follows the ratio (C2/C1) of capacitance (C2) of a second capacitor (82b) to capacitance (C1) of a first capacitor (82a).
