Document Type and Number:
WIPO Patent Application WO/2023/090263
Kind Code:
A1
Abstract:
[Problem] To provide a power conversion device that can acquire an effect of impedance balance over a wide bandwidth, and that can efficiently suppress noise caused by a common mode current. [Solution] A resistor 33R is connected between a positive electrode-side parasitic capacitance generation point P and a housing 15, and a resistor 34R is connected between a negative electrode-side parasitic capacitance generation point N and the housing 15. When the impedance of the inductance of a positive electrode-side path 16 is denoted as Zv, the impedance of the inductance of a negative electrode-side path 17 is denoted as Zg, the impedance including the resistor 33R and a capacitor between the positive electrode-side parasitic capacitance generation point P and the housing 15 is denoted as Zt, and the impedance including the resistor 34R and a capacitor between the negative electrode-side parasitic capacitance generation point N and the housing 15 is denoted as Zb, Zt and Zb are set on the basis of a balance condition of a bridge circuit constituted by Zv, Zg, Zt, and Zb.
