POWER CONVERSION DEVICE

A capacitor (C) has a parasitic inductance component (Lp) and is electrically connected between a positive line (PL1) and a negative line (NL). A converter (10) includes a reactor (Lc) provided in the positive line (PL1) and performs voltage conversion of a DC voltage smoothed by a capacitor (C1). A...

More Information
Summary:A capacitor (C) has a parasitic inductance component (Lp) and is electrically connected between a positive line (PL1) and a negative line (NL). A converter (10) includes a reactor (Lc) provided in the positive line (PL1) and performs voltage conversion of a DC voltage smoothed by a capacitor (C1). An inverter (20) performs DC-AC conversion between the converter (10) and an AC motor (M) by switching control. A path (PATH1) of the positive line (PL1) which connects a DC power supply (B) and the capacitor (C) has an inductance smaller than an inductance of a path (PATH2) of the negative line (NL) which connects the DC power supply (B) and the capacitor (C). A difference between the inductance of the path (PATH2) and the inductance of the path (PATH1) is less than twice the parasitic inductance component (Lp).
