WIPO Patent Application WO/2023/228642
Kind Code:
A1
Abstract:
[Problem] To provide an inverter device that can effectively reduce noise by a common mode current while having a reduced size. [Solution] The inverter device comprises: an input side common mode coil 67 that is inserted into a single phase input unit of an inverter circuit 34; and an output side common mode coil 66 that is inserted into a three phase output unit of the inverter circuit 34. The input side common mode coil 67 and the output side common mode coil 66 are in an integral structure with a common core. Two wires on the positive side and the negative side of the input side common mode coil 67 are bifilar wound onto the core. Three wires of the UVW phases of the output side common mode coil 66 are trifilar wound onto the core.
