PROBLEM TO BE SOLVED: To achieve reduction in size and cost by reducing the number of parts, and also reduces noises generated from a power converting apparatus. SOLUTION: Capacitors for anti-resonance corresponding to the reactors in the same number of the phases of power supply has been connected. However, in this input line filter, a reactor 5, having an auxiliary reactor, is provided between the commercial AC power supply 1 and the input terminal of the power converting apparatus 10 and the capacitor 2 for anti-resonance is connected, only to auxiliary reactor which reduces the number of capacitors and achieve reduction in size and cost. |
