PURPOSE:To protect an inverter element by connecting the series connection of a reactor and a capacitor to a power source, thereby suppressing the instantaneously abrupt variation of the current. CONSTITUTION:Motor M1, M2 are respectively connected to inverters N1, N2, and inverter motor systems are connected through reactors L1, L2 to a DC power source. Since these reactors L1, L2 have motor drive balance and filtering function, they can individually controls the motors M1, M2. The reactor L1, a capacitor C2 and the reactor L2, a capacitor C2 are respectively always connected in series of the reactor and the condenser to the inverters N1, N2, the series connections of the reactor and the capacitor similarly becomes from the power source, and this series connection can suppress the instantaneously abrupt variation of the current. |
