Abstract

PURPOSE:To sufficiently suppress interfering current component by switching either of the constitution of a filter or the constant of the filter, or both of them corresponding to the specified operating frequencies of an inverter. CONSTITUTION:An LC filter 31 is composed of the LC filter portion comprising the first filter reactor L1, the second filter reactor L2, the first filter capacitor C1, and the second filter capacitor C2; and a switching device S1 which is switched to either Aa or A2. The switching device S1 is switched to A1 when an input frequency is lower than the specified frequency, and switched to A2 when the input frequency is higher.
