Abstract

PURPOSE:To detect the trouble of the inverter rapidly by each flowing currents through the primary conductors of a current detector in reversed polarity when the device is normal and flowing currents in the same direction when the device gets trouble. CONSTITUTION:When a switch 2 is closed and each inverter 5, 6 is operated, the currents of the first inverter 5 and the second inverter 6 flow through several primary conductor of the current detector 7 in reversed polarity, and the currents of the second filter capacitor 4a are zero because the plus side and the minus side also flow in reversed polarity in the currents of the filter capacitor. When there happens an accident in the inverter 5 or 6 under this condition, the currents of the accident flow through the primary conductors in the same direction, and the currents of the accident added by means of the current detector 7 are detected.
