Document Type and Number:
WIPO Patent Application WO/2020/208825
Kind Code:
A1
Abstract:
A power conversion device (100) is provided with: a converter (4) and an inverter (5); a common mode choke coil (2) connected between the converter (4) and a commercial AC power source (1) that is an AC power source; Y capacitors (7a, 7b, 8a, 8b), which are AC-side interphase capacitors connected between power lines that connect the AC power source and the converter (4); and Y capacitors (9a, 9b), which are DC-side interphase capacitors connected between power lines that connect the converter (4) and the inverter (5). A shared grounding line (21) is used as the respective grounds of the AC-side interphase capacitors and the DC-side interphase capacitors. Ferrite beads (12, 13, 14), which are electronic parts having an inductance component, are respectively provided to wiring between the AC-side interphase capacitors and the grounding line (21), and to wiring between the DC-side interphase capacitors and the grounding line (21).
